This setup prevents users from being forced into the HTTPS version of the main site when a self-signed SSL certificate is in use.\n\n*Reflection:*\n\"What exactly causes the whole site to redirect to HTTPS? Is it a configuration setting or plugin causing this behavior?\"\n\n*Creative Perspective:*\n\"Could there be hidden settings within WordPress or the hosting environment that enforce global SSL? Might there be a common misunderstanding about SSL configuration that could be influencing this redirect?\"\n\n**2.2 Analyze the Information:**\nThere may be configurations in the WordPress settings, .htaccess files, or web server settings (like Apache or Nginx) that force HTTPS across the entire site. Analyzing these settings can provide clarity on what's causing the global redirect.\n\n*Reflection:*\n\"Am I thoroughly examining all possible sources for the HTTPS redirection? Is there a configuration override being applied at a higher level?\"\n\n*Creative Perspective:*\n\"Could there be extra plugins, themes, or server configurations unknowingly adding an HTTPS redirect? Is there a way to leverage these settings to gain more control over the SSL application?\"\n\n**2.3 Generate Hypotheses:**\n1. A misconfigured .htaccess file is redirecting all traffic to HTTPS. (Confidence: 0.7, Creative: 0.4)\n2. WordPress settings might be influenced by a third-party plugin enforcing SSL site-wide. (Confidence: 0.6, Creative: 0.5)\n3. The web hosting platform settings, like in CPanel, might be forcing HTTPS universally. (Confidence: 0.5, Creative: 0.5)\n4. The WP_FORCE_SSL_LOGIN and WP_FORCE_SSL_ADMIN constants in wp-config.php are set incorrectly. (Confidence: 0.8, Creative: 0.6)\n5. A previous developer might have included hardcoded HTTPS redirects in the theme's functions.php file. (Confidence: 0.5, Creative: 0.6)\n6. Server-level HTTPS redirect rules in Apache or Nginx configurations are affecting site access. (Confidence: 0.7, Creative: 0.4)\n7. A misunderstanding about setting permalinks is causing universal HTTPS redirects. (Confidence: 0.4, Creative: 0.5)\n8. There is a browser caching issue remembering HTTPS URLs for the main site. (Confidence: 0.6, Creative: 0.3)\n9. A CDN configuration is forcing HTTPS for all site content. (Confidence: 0.3, Creative: 0.4)\n10.

Does it directly address the core issue with minimal disruptions?\"\n\n*Creative Perspective:*\n\"Ideally, leveraging this hypothesis could streamline admin use of SSL without affecting the broader user experience.\"\n\n**2.7 Implement the Hypothesis:**\n1. Verify the wp-config.php file for WP_FORCE_SSL_LOGIN and WP_FORCE_SSL_ADMIN constants.\n2. Modify these constants to ensure SSL is only enforced on the admin interface.\n\n*Reflection:*\n\"Are these steps adequately detailed to implement changes smoothly? The changes should not negatively impact existing site functionality.\"\n\n*Creative Perspective:*\n\"Exploring alternative creative backups or parallels might reveal opportunities for automation or enhanced security during implementation.\"\n\n**2.8 Monitor and Review Progress:**\nReview the site access after changes to ensure SSL is appropriately enforced only for the admin area.\n\n*Reflection:*\n\"Is the SSL usage streamlined for the admin area while the site remains accessible via HTTP? What additional configurations or monitoring steps are required?\"\n\n*Creative Perspective:*\n\"Are there additional benefits or optimization strategies that have emerged? Do error logs or user feedback suggest any unintended consequences or areas for further refinement?\"\n\n**2.9 Reflect and Capture Insights:**\nCompile observations and adjustments that were effective, making a note of strategies and fallbacks that proved valuable.\n\n*Reflection:*\n\"What new insights have resulted, and how can they be applied to future SSL configuration challenges in WordPress?\"\n\n*Creative Perspective:*\n\"Are there innovative solutions or methods that could be abstracted and applied to different systems facing similar challenges?\"\n\n[end sys2]\n\n[sys1]\nTo implement SSL only for the WordPress admin interface:\n- Update the wp-config.php file with `define('FORCE_SSL_ADMIN', true);` to ensure SSL is applied only to the admin panel.\n- Check for any forced HTTPS redirects within .htaccess or server configurations and adjust as necessary to prevent HTTPS enforcement site-wide.\n- Clear any caching that might be remembering previous redirects and ensure no third-party plugins are enforcing global HTTPS.\n\nMonitoring the effect of these changes is essential to confirm that SSL is being used appropriately and adjust as needed.\n[end sys1]","behavior":"degenerate_repetition","conversation_hash":"1f6af93819a79d6517b3e6c5ffe763cd","conversation_redacted":false,"conversation_toxic":false,"country":"","empty_output":false,"evidence_codes":[],"label":"absent","label_present":false,"label_qualified":false,"label_source":"Final dense release","language":"English","model":"gpt-4o-2024-08-06","n_chars":14777,"n_turns_in_conversation":1,"n_words":2092,"source_row_offset":28002,"source_shard":"turns-00045.parquet","timestamp":"Wed, 06 Nov 2024 02:38:44 GMT","turn_id":"f3e9b7c790bf955a2231ac12","turn_index":0,"user_text":"You are a helpful assistant generating synthetic data that captures *System 1* and *System 2* thinking, *creativity*, and *metacognitive reflection*.

From then on, reflected solutions to SDEs and BSDEs were investigated by many authors. For one-dimensional case, El Karoui [@EL], El Karoui and Chaleyat-Maurel [@EC] and Yamada [@Y] studied reflected SDEs on a half-line, and El Karoui et al.[@EKPPQ] obtained the solvability of reflected BSDEs. For multidimensional case, the existence of weak solutions to reflected SDEs on a smooth domain was proved by Stroock and Varadhan [@SV]. After that, Tanaka [@T] solved the similar problem on a convex domain by a direct approach based on the solution to Skorokhod problem. Furthermore, Lions and Sznitman [@LS] extended these results to a non convex domain. On the other hand, the corresponding results for reflected BSDEs can be found in Gegout-Petit and Pardoux [@GP], Ramasubramanian [@R] and Hu and Tang [@HT], etc..\\\nMotivated by uncertainty problems, risk measures and the superhedging in finance, Peng [@P2; @P3] introduced a framework of time consistent nonlinear expectation $\\mathbb{E}[\\cdot]$, in which a new type of Brownian motion is constructed and corresponding stochastic calculus was established. Moreover, Denis et al. [@DHP] derived that $G$-expectation $\\mathbb{E}[\\cdot]$ can be viewed as an upper expectation with respect to a weakly compact family $\\mathcal{P}$ of probability measures, and they naturally defined a Choquet capacity $\\bar{C}(\\cdot)$ on $\\Omega$: $$\\bar{C}(A)=\\sup_{\\mathbb{P}\\in\\mathcal{P}}\\mathbb{P}(A),\\ A\\subset\\Omega.$$ Thus, many concepts from capacity theory can be introduced to $G$-framework, especially, the notion of \u201cquasi-surely\u201d which means that a property holds true outside a polar set, i.e., outside a set $A\\subset \\Omega$ satisfies $\\bar{C}(A)=0$. Using the notation of \u201cquasi-surely\u201d, Gao [@G] and Lin and Bai [@BL] have already worked on the solvability to SDEs driven by $G$-Brownian motion.\\\nMeanwhile, Soner et al. [@STZ3; @STZ2; @STZ1] have established a complete theory for 2BSDEs under a uniform Lipschitz conditions which is closely related to $G$-expectation. In their framework, they also issued a similar notion, but their definition of \u201cquasi-surely\u201d means that a property holds $\\mathbb{P}$-a.s. for every probability measure $\\mathbb{P}$ in a non-dominated class of mutually singular measures. We notice that this definition is a little different compared to that made by $G$-capacity $\\bar{C}(\\cdot)$ in Denis et al. [@DHP], since by their definition the null set $A^\\mathbb{P}$ under each $\\mathbb{P}\\in\\mathcal{P}$ could be different. More recently, Matoussi et al. [@MPZ] have studied the problem of reflected 2BSDEs with a lower obstacle .\\\nThe aim of this paper is to study the existence and uniqueness of solutions to stochastic differential equations driven by $G$-Brownian motion with reflecting boundary conditions (RGSDEs) in the sense of \u201cquasi-surely\u201d defined by Denis et al. [@DHP]. The scalar valued RGSDE we consider is defined as following: $$\\label{ABC}\n\\left\\{\\begin{aligned}\n&X_t=x+\\int^t_0 f_s(X_s)ds+\\int^t_0 h_s(X_s)d\\langle B \\rangle_s +\\int^t_0 g_s(X_s) dB_s +K_t, \\ q.s.,\\ 0\\leq t\\leq T; \\\\\n&X_t\\geq S_t; \\int^T_0 (X_t-S_t)dK_t=0,\n\\end{aligned}\\right.$$ where $\\langle B\\rangle$ is the quadratic variation process of $G$-Brownian motion $B$, and $K$ is an increasing process which pushes the solution $X$ upwards to be remaining above the obstacle $S$ in a minimal way. Similarly to classical reflected SDEs, the uniqueness result is deduced from a priori estimates and a solution in $M^p_G([0, T])$ to (\\[ABC\\]) can be constructed by fixed-point iteration. To establish the comparison theorem, we need to develop an extension of $G$-It\u00f4 formula to deal with such process $X$ involves both the stochastic integrals and an increasing process. This extended $G$-It\u00f4\u2019s formula can have its own interest and may be used in other situation.\\\nThis paper is organized as follows: Section 2 introduces some notations and results in $G$-framework which is necessary for what follows. Section 3 introduces the stochastic calculus with respect to an increasing process in $G$-framework. Section 4 studies the reflected $G$-Brownian motion, while Section 5 is our main results.\n\n$G$-Brownian motion, $G$-capacity and $G$-stochastic calculus\n=============================================================\n\nThe main purpose of this section is to recall some preliminary results in $G$-framework which are needed in the sequel. The reader interested in a more detailed description of these notions is referred to Denis et al. [@DHP], Gao [@G] and Peng [@P3].\n\n$G$-Brownian motion\n-------------------\n\nAdapting the approach in Peng [@P3], let $\\Omega$ be the space of all $\\mathbb{R}$-valued continuous paths with $\\omega_0 =0$ equipped with the distance $$\\rho(\\omega^1, \\omega^2):=\\sum^\\infty_{N=1} 2^{-N} [(\\max_\n{t\\in[0,N]} | \\omega^1_t-\\omega^2_t|) \\wedge 1],$$ $B$ the canonical process and $C_{l,Lip}\n(\\mathbb{R}^{n})$ the collection of all local Lipschitz functions on $\\mathbb{R}^{n}$. For a fixed $T\\geq0$, the space of finite dimensional cylinder random variables is defined by $$L_{ip}^0 (\\Omega_T):=\\{\\varphi(B_{t_1}, \\ldots, B_{t_n}):n\\geq\n1, 0\\leq t_1\\leq \\ldots\\leq t_n \\leq T, \\varphi \\in C_{l,Lip}\n(\\mathbb{R}^{n})\\},$$ on which $\\mathbb{E}[\\cdot]$ is a sublinear functional satisfying: for all $X$, $Y\\in C_{l,Lip}(\\mathbb{R}^{n})$,\n\n**Monotonicity:** if $X\\geq Y$, then $\\mathbb{E}[X]\\geq\\mathbb{E}[Y];$\n\n**Sub-additivity**:\u00a0$\\mathbb{E}[X]-\\mathbb{E}[Y]\\leq\\mathbb{E}[X-Y]$;\n\n**Positive homogeneity:**\u00a0$\\mathbb{E}[\\lambda\nX]=\\lambda\\mathbb{E}[X]$, for all $\\lambda\\geq 0$;\n\n**Constant translatability:**\u00a0$\\mathbb{E}[X+c]=\\mathbb{E}[X]+c$, for all $c\\in\\mathbb{R}$.\n\nThe triple $(\\Omega, L_{ip}^0 (\\Omega_T), \\mathbb{E})$ is called a sublinear expectation space.\n\n\\[de 2.1.4\\] A scalar valued random variable $X\\in L_{ip}^0 (\\Omega_T)$ is $G$-normal distributed with parameters $(0, [\\underline{\\sigma}^2, \\overline{\\sigma}^2])$, i.e., $X\\sim\\mathcal{N}(0, [\\underline{\\sigma}^2, \\overline{\\sigma}^2])$, if for each $\\varphi \\in C_{l,Lip} (\\mathbb{R})$, $u(t, x):=\\mathbb{E}[\\varphi(x+\\sqrt{t}X)]$ is a viscosity solution to the following PDE on $[0, +\\infty)\\times\\mathbb{R}$: $$\\left\\{\\begin{aligned}\n&\\frac{\\partial u}{\\partial t}-G\\bigg(\\frac{\\partial^2 u}{\\partial x^2}\\bigg)=0;\\\\\n&u|_{t=0} = \\varphi,\n\\end{aligned}\\right.$$ where $$G(a):=\\frac{1}{2} (a^+\\overline{\\sigma}^2-a^-\\underline{\\sigma}^2),\\ a\\in\\mathbb{R}.$$\n\nWithout loss of generality, we always assume that $\\overline{\\sigma}^2=1$ in what follows.\n\n\\[de 2.1.5\\] We call a sublinear expectation $\\mathbb{E}: L_{ip}^0(\\Omega_T) \\rightarrow \\mathbb{R}$ a $G$-expectation if the canonical process $B$ is a $G$-Brownian motion under $\\mathbb{E}[\\cdot]$, that is, for all $0\\leq s\\leq t\\leq T$, the increment $B_t - B_s \\sim \\mathcal{N}(0, [(t-s)\\underline{\\sigma}^2, (t-s)])$ and for all $n\\in\\mathbb{N}$, $0\\leq\nt_1\\leq\\ldots\\leq t_n\\leq t$, and $\\varphi\\in\nC_{l,Lip}(\\mathbb{R}^{n})$, $$\\mathbb{E}[\\varphi(B_{t_1},\\ldots,B_{t_{n-1}},B_{t_n}-B_{t_{n-1}})]=\\mathbb{E}[\\psi(B_{t_1},\\ldots,B_{t_{n-1}})],$$ where $\\psi(x_1,\\ldots,x_{n-1}):=\\mathbb{E}[\\varphi(x_1,\\ldots,x_{n-1},\\sqrt{t_n-t_{n-1}}B_1)]$.\n\nFor $p\\geq 1$, we denote by $L^p_G(\\Omega_T)$ the completion of $L_{ip}^0(\\Omega_T)$ under the Banach norm $\\mathbb{E}[|\\cdot|^p]^\\frac{1}{p}$.\n\n$G$-capacity\n------------\n\nDerived in Denis et al. [@DHP], $G$-expectation $\\mathbb{E}[\\cdot]$ can be viewed as an upper expectation $\\bar{\\mathbb{E}}[\\cdot]$ associated with a weakly compact family $\\mathcal{P}$ on $L^1_G(\\Omega_T)$, i.e., $$\\mathbb{E}[X]=\\bar{\\mathbb{E}}[X]:=\\sup_{\\mathbb{P}\\in\\mathcal{P}}E^\\mathbb{P}[X],\\ X\\in L^1_G(\\Omega_T).$$ In this sense, the domain of $G$-expectation can be extended from $L^1_G(\\Omega_T)$ to the space of all $\\mathcal{B}(\\Omega_T)$ measurable random variables $L^0(\\Omega_T)$ by setting $$\\bar{\\mathbb{E}}[X]:=\\sup_{\\mathbb{P}\\in\\mathcal{P}}E^\\mathbb{P}[X],\\ X\\in L^0(\\Omega_T).$$ Naturally, we can define a corresponding regular Choquet capacity on $\\Omega$: $$\\bar{C}(A):=\\sup_{\\mathbb{P}\\in\\mathcal{P}}\\mathbb{P}(A),\\ A\\in\\mathcal{B}(\\Omega),$$ with respect to which, we have the following notions:\n\n\\[de 2.1.6\\] A set $A\\in\\mathcal{B}(\\Omega)$ is called polar if $\\bar{C}(A)=0.$ A property is said to hold quasi-surely (q.s.) if it holds outside a polar set.\n\n\\[qcon\\] A random variable $X$ is said to be quasi-continuous (q.c.) if for arbitrarily small $\\varepsilon>0$, there exists an open set $O\\subset \\Omega$ with $\\bar{C}(O)<\\varepsilon$ such that $X$ is continuous in $\\omega$ on $O^c$.\n\nWe say that a random variable $X$ has a q.c. version if there exists a q.c. random variable $Y$ such that $X=Y$, q.s..\n\nIn a language of $G$-capacity, Denis et al. [@DHP] proved that for $p\\geq 1$, the function space $L^p_G(\\Omega_T)$ has a dual representation which is much more explicit to verify:\n\n\\[lpg\\] $$L^p_G(\\Omega_T)=\\{X\\in L^0(\\Omega_T): X\\ has\\ a\\ q.c.\\ version,\\ \\lim_{N\\rightarrow+\\infty}\\bar{\\mathbb{E}}[|X|^p{\\bf{1}}_{|X|>N}]=0\\}.$$\n\nUnlike in classical framework, the downwards monotone convergence theorem only holds true for a sequence of random variables from a subset of $L^0(\\Omega_T)$ (cf. Theorem 31 in Denis et al. [@DHP]).\n\n\\[CTD\\] Let $\\{X_n\\}_{n\\in\\mathbb{N}}\\subset L_G^1(\\Omega_T)$ be such that $X_n\\downarrow X$, q.s., then $\\bar{\\mathbb{E}}[X_n]\\downarrow\\bar{\\mathbb{E}}[X]$.\n\nWe note that dominated convergence theorem does not exist in $G$-framework, even though we assume that $\\{X_n\\}_{n\\in\\mathbb{N}}$ is a sequence in $L^1_G(\\Omega_T)$. The lack of this theorem is one of the main difficulties we shall overcome in the following sections.\n\n$G$-stochastic calculus\n-----------------------\n\nIn Peng [@P3], generalized It$\\hat{o}$ integrals with respect to $G$-Brownian motion are established:\n\n\\[caocao\\] A partition of $[0,T]$ is a finite ordered subset $\\pi^N_{[0, T]}=\\{t_0, t_1,\\ldots,t_N\\}$ such that $0=t_00$ such that $K_T(\\omega)0$, there exists a $\\delta>0$ such that for all $|t-s|<\\delta$, $|X_t(\\omega)-X_s(\\omega|)<\\varepsilon/M_\\omega$. It is sufficient to choose an $N_0\\in\\mathbb{N}$ such that $\\mu(\\pi^{N_0}_{[0,T]})<\\delta$, then, for all $N>N_0$, $$\\bigg|\\mathcal{V}_{[0,T]}^N(X, K)(\\omega)-\\bigg(\\int^T_0X_tdK_t\\bigg)(\\omega)\\bigg|<\\varepsilon,$$ from which we deduce that $$\\label{icon}\n\\mathcal{V}_{[0,T]}^N(X, K)\\rightarrow \\int^T_0X_tdK_t,\\ q.s.,\\ as\\ N\\rightarrow +\\infty.$$ The construction of the sequence (\\[constr\\]) provides a q.s. approximation to the stochastic integral $\\int^T_0X_tdK_t$. We note that the convergence (\\[icon\\]) depends only on the sequence of refined partitions $(\\pi^N_{[0,T]})_{N\\in\\mathbb{N}}$ but is independent of the selection of the points of division and the representatives $X_{u^N_k}$ on $[t^N_k, t^N_{k+1})$, $k=0, 1,\\ldots, N-1$, $N\\in\\mathbb{N}$.\n\nThe following propositions can be verified directly by Definition \\[increa\\] and the Heine-Cantor theorem.\n\n\\[propo1\\] Let $X$, $X^1$ and $X^2\\in M_c([0, T])$, $K$, $K^1$ and $K^2\\in M_I([0, T])$ and $0\\leq s\\leq r \\leq t\\leq T$, then we have\n\n$\\int^t_sX_udK_u=\\int^r_sX_udK_u+\\int^t_rX_udK_u$, q.s.;\n\n$\\int^t_s(\\alpha X^1_u+X^2_u)dK_u=\\alpha\\int^t_sX^1_udK_u+\\int^t_sX^2_udK_u$, q.s., where $\\alpha\\in L^0(\\Omega_s)$;\n\n\\[sum\\] $\\int^t_sX_ud(K^1\\pm K^2)_u=\\int^t_sX_udK^1_u \\pm \\int^t_sX_udK^2_u$, q.s..\n\nBy a classical argument, a q.s. continuous and bounded variation process can be viewed as the difference of two increasing processes $K_1-K_2$, where $K_1$ and $K_2\\in M_I([0, T])$. By Proposition \\[propo1\\] (\\[sum\\]), the stochastic integral with respect to $K_1-K_2$ can be defined in the same way as Definition \\[increa\\].\n\nLet $X\\in M_c([0, T])$ and $K\\in M_I([0, T])$, the integral $\\int^\\cdot_0X_sdK_s$ is q.s. continuous in $t$, i.e., $(\\int^t_0X_sdK_s)_{0\\leq t\\leq T}\\in M_c([0, T])$.\n\nAs showed above, (\\[II\\]) defines a random variable $\\int^T_0X_tdK_t$ in $L^0(\\Omega_T)$. A nature question comes out: if we assume that for some appropriate $p$ and $q$, $X\\in M^p_G([0, T])$ and $K\\in M^q_G([0, T])$, this random variable $\\int^T_0X_tdK_t$ can be verified as an element in $L^1_G(\\Omega_T)$ or not. In general, the answer is negative. That is because the integrability of $X$ and $K$ can not ensure the quasi-continuity of $\\int^T_0X_tdK_t$ (cf. Definition \\[qcon\\] and Theorem \\[lpg\\]). More precisely, the pathwise convergence (\\[icon\\]) is not necessarily uniform in $\\omega$ outside a polar set $A$, and it is hard to verify directly the convergence in the sense of $L^1_G(\\Omega_T)$ due to the lack of dominated convergence theorem in $G$-framework. But in some special cases, a proper sequence $\\{\\mathcal{V}_{[0,T]}^N(X, K)\\}_{N\\in\\mathbb{N}}$ approximating to $\\int^T_0X_tdK_t$ can be found, so that the quasi-continuity is inherited during the approximation.\n\nLet $K\\in M_I([0, T])\\cap M^2_G([0, T])$, $K_T\\in L^2_G(\\Omega_T)$ and $\\phi: \\mathbb{R}\\rightarrow \\mathbb{R}$ is a Lipschitz function, then $\\int^T_0\\phi(K_t)dK_t$ is an element in $L^1_G(\\Omega_T)$.\n\n**Proof:** Consider a sequence of refining partitions $\\{\\pi^N_{[0,T]}\\}_{N\\in\\mathbb{N}}$ mentioned in Remark \\[sequen\\] and define the sequence of approximation: for $N\\in\\mathbb{N}$, $$\\mathcal{V}_{[0,T]}^N(\\phi(K), K)(\\omega)\n=\\sum^{N-1}_{k=0}\n\\phi(K_{t^N_k})(\\omega)(K_{t^N_{k+1}}(\\omega)-K_{t^N_k}(\\omega)).$$ From the explanation in Remark \\[remconna\\], we can always assume that at the points of division, $K_{t^N_k}\\in L^2_G(\\Omega_T)$, $k =0, 1,\\ldots, N-1$, $N\\in \\mathbb{N}$. Since $K$ is increasing, we have $$\\begin{aligned}\n\\bigg|\\mathcal{V}_{[0,T]}^N(\\phi(K), K)-\\int^T_0 \\phi(K_t)dK_t\\bigg|\n\\leq&\\bigg|\\int^T_0 \\bigg(\\sum^{N-1}_{k=0}|K_{t^N_{k+1}}-K_{t^N_k}|I_{[t^N_k, t^N_{k+1})}(t)\\bigg) dK_t\\bigg|\\\\\n\\leq&\\sum^{N-1}_{k=0}|K_{t^N_{k+1}}-K_{t^N_k}|^2 \\downarrow 0,\\ q.s.,\\ as\\ N\\rightarrow +\\infty.\\end{aligned}$$ On the other hand, it is easy to verify by Theorem \\[lpg\\] that for all $N\\in\\mathbb{N}$, $\\mathcal{V}_{[0,T]}^N(\\phi(K), K)$ and $\\sum^{N-1}_{k=0}|K_{t^N_{k+1}}-K_{t^N_k}|^2\\in L^1_G(\\Omega_T)$. Then, by Theorem \\[CTD\\], $$\\bar{\\mathbb{E}}\\bigg[\\bigg|\\mathcal{V}_{[0,T]}^N(\\phi(K), K)-\\int^T_0 \\phi(K_t)dK_t\\bigg|\\bigg]\n\\leq \\bar{\\mathbb{E}}\\bigg[\\sum^{N-1}_{k=0}|K_{t^N_{k+1}}-K_{t^N_k}|^2\\bigg]\\downarrow0,\\ as\\ N\\rightarrow +\\infty.$$ From the completeness of $L^1_G(\\Omega_T)$ under $\\bar{\\mathbb{E}}[|\\cdot|]$, we deduce the desired result.$\\square$\n\nTo verify that for all $N\\in \\mathbb{N}$, $\\mathcal{V}_{[0,T]}^N(\\phi(K), K)$ and $\\sum^{N-1}_{k=0}|K_{t^N_{k+1}}-K_{t^N_k}|^2\\in L^1_G(\\Omega_T)$, we should assume here that $K_T\\in L^2_G(\\Omega_T)$.\n\n\\[boudiff\\] Let $X$ be a q.s. continuous $G$-It\u00f4 process such that $$\\label{gito}\nX_t= x+\\int^t_0 f_sds+\\int^t_0h_sd\\langle\nB\\rangle_s+\\int^t_0g_sdB_s,\\ 0\\leq t\\leq T,$$ where $f$, $h$ and $g$ are elements in $M^p_G([0, T])$, $p>2$.

By the definitions of stochastic integrals and the BDG type inequalities, one can verify that for each $t\\in [0, T]$, $X_t\\in L^p_G(\\Omega_t)$. Therefore, for all $N\\in\\mathbb{N}$, $\\mathcal{V}_{[0,T]}^N(X, K)\\in L^1_G(\\Omega_T)$. Applying the BDG type inequalities, we have $$\\begin{aligned}\n\\bar{\\mathbb{E}}[\\sup_{s\\leq u\\leq t}|X_u-X_s|^p]\n\\leq C\\bigg(|t-s|^{p-1}\\bigg(\\int^t_s(\\bar{\\mathbb{E}}[|f_u|^p]\n&+\\bar{\\mathbb{E}}[|h_u|^p])du\\bigg)\\\\\n&+|t-s|^{\\frac{p}{2}-1}\\int^t_s\\bar{\\mathbb{E}}[|g_u|^p]du\\bigg).\\end{aligned}$$ Thus, $$\\begin{aligned}\n\\label{za}\n&\\bar{\\mathbb{E}}[\\sup_{k\\in[0, N)\\cap\\mathbb{N}}\\sup_{t_k\\leq t\\leq t_{k+1}}|X_t-X_{t^N_k}|^p]\n\\leq\\bar{\\mathbb{E}}\\bigg[\\sum_{k=0}^{N-1}\\sup_{t^N_k\\leq t\\leq t^N_{k+1}}|X_t-X_{t^N_k}|^p\\bigg]\\notag\\\\\n\\leq&C\\sum_{k=0}^{N-1}\\bigg(\\int^{t^N_{k+1}}_{t^N_k}(|t^N_{k+1}-t^N_k|^{p-1}(\\bar{\\mathbb{E}}[|f_t|^p]+\\bar{\\mathbb{E}}[|h_t|^p])\n+|t^N_{k+1}-t^N_k|^{\\frac{p}{2}-1}\\bar{\\mathbb{E}}[|g_t|^p])dt\\bigg)\\\\\n\\leq&C\\bigg(\\mu(\\pi^N_{[0,T]})^{p-1}\\int^T_0(\\bar{\\mathbb{E}}[|f_t|^p]+\\bar{\\mathbb{E}}[|h_t|^p])dt+\\mu(\\pi^N_{[0,T]})^{\\frac{p}{2}-1}\\int^T_0\\bar{\\mathbb{E}}[|g_t|^p]dt\\bigg).\\notag\\end{aligned}$$ From the integrability of $f$, $h$ and $g$, we have $$\\bar{\\mathbb{E}}[\\sup_{k\\in[0, N)\\cap\\mathbb{N}}\\sup_{t_k\\leq t\\leq t_{k+1}}|X_t-X_{t^N_k}|^p]\n\\leq CM(\\mu(\\pi^N_{[0,T]})^{p-1}+\\mu(\\pi^N_{[0,T]})^{\\frac{p}{2}-1}).\\notag$$ For $N\\in\\mathbb{N}$, we calculate $$\\begin{aligned}\n&\\bigg|\\mathcal{V}_{[0,T]}^N(X, K)-\\int^T_0 X_tdK_t\\bigg|\\leq \n\\int^T_0 \\bigg|\\sum^{N-1}_{k=0}X_{t^N_k}I_{[t^N_k, t^N_{k+1})}(t)-X_t\\bigg|dK_t\\\\\n\\leq&\\sup_{0\\leq t\\leq T}\\bigg|\\sum^{N-1}_{k=0}X_{t^N_k}I_{[t^N_k, t^N_{k+1})}(t)-X_t\\bigg|K_T\\leq K_T\\sup_{k\\in[0, N)\\cap\\mathbb{N}}\\sup_{t_k\\leq t< t_{k+1}}|X_t-X_{t^N_k}|.\\end{aligned}$$ Consequently, $$\\begin{array}{r@{\\ }l}\n\\bar{\\mathbb{E}}[|\\mathcal{V}_{[0,T]}^N(X, K)-\\int^T_0 X_tdK_t|]\n\\leq&\\bar{\\mathbb{E}}[K_T\\sup_{k\\in[0, N)\\cap\\mathbb{N}}\\sup_{t_k\\leq t< t_{k+1}}|X_t-X_{t^N_k}|]\\\\[6pt]\n\\leq&\n(\\bar{\\mathbb{E}}[\\sup_{k\\in[0, N)\\cap\\mathbb{N}}\\sup_{t_k\\leq t< t_{k+1}}|X_t-X_{t^N_k}|^p])^{\\frac{1}{p}}(\\bar{\\mathbb{E}}[K^q_T])^{\\frac{1}{q}} \\\\[6pt]\n\\leq&CM(\\mu(\\pi^N_{[0,T]})^{p-1}+\\mu(\\pi^N_{[0,T]})^{\\frac{p}{2}-1})^{\\frac{1}{p}}\\rightarrow 0,\\ as\\ N\\rightarrow +\\infty.\n\\end{array}$$ The desired result follows.$\\square$\n\nAn extension of $G$-It\u00f4\u2019s formula\n---------------------------------\n\nFor $0\\leq s\\leq t\\leq T$, consider a sum of a $G$-It\u00f4 process and an increasing process $K$: $$X_t= X_s + \\int^t_s f_udu+\\int^t_sh_ud\\langle\nB\\rangle_u+\\int^t_sg_udB_u+K_t-K_s.$$\n\n\\[itolem\\] Let $\\Phi\\in \\mathcal{C}^2(\\mathbb{R})$ be a real function with bounded and Lipschitz derivatives.

Then, we can proceed similarly to that in Peng [@P3] to treat with $I^N_1$ and $I^N_2$.\\\nOn the other hand, due to the boundedness of $\\frac{d^2\\Phi}{dx^2}$ and the boundedness and uniformly continuity of paths $M^X_\\cdot(\\omega)$ and $K_\\cdot(\\omega)$ on $[0, T]$, for $\\omega\\in A^c$, we can easily get that $I^N_3$ and $I^N_4$ are q.s. vanished.\\\nFor $I^N_5$, we calculate $$\\begin{aligned}\n|I^N_5|&\\leq \\frac{C}{2}\\sum^{2^{N}-1}_{k=0}|\\xi^{2^N}_{k}-X_{t^{2^N}_{k}}||M^X_{t^{2^N}_{k+1}}-M^X_{t^{2^N}_k}|^2\\\\\n&\\leq \\frac{C}{2}\\bigg(\\sum^{2^{N}-1}_{k=0}|(\\xi^1)^{2^N}_{k}-M^X_{t^{2^N}_{k}}||M^X_{t^{2^N}_{k+1}}-M^X_{t^{2^N}_k}|^2+\\sum^{2^{N}-1}_{k=0}|(\\xi^2)^{2^N}_{k}-K_{t^{2^N}_{k}}||M^X_{t^{2^N}_{k+1}}-M^X_{t^{2^N}_k}|^2\\bigg),\\end{aligned}$$ where $(\\xi^1)^{2^N}_k$ satisfies $M^X_{t^{2^N}_k}\\wedge M^X_{t^{2^N}_{k+1}} \\leq (\\xi^1)^{2^N}_k\n\\leq M^X_{t^{2^N}_k}\\vee M^X_{t^{2^N}_{k+1}}$ and $(\\xi^2)^{2^N}_k$ satisfies $K_{t^{2^N}_k}\\leq (\\xi^2)^{2^N}_k\n\\leq K_{t^{2^N}_{k+1}}$, q.s.. The result in Peng [@P3] shows that the first part converges to 0 in $M^2_G([0, T])$ while the second part is vanished as a result of the uniformly continuity of paths $K_\\cdot(\\Omega)$ on $[0, T]$, for $\\omega\\in A^c$, and the q.s. boundedness of the quadratic variation of the $G$-It\u00f4 part $M^X$.\\\nFor $I^N_6$, it converges to $\\int^t_s\\frac{d\\Phi}{dx}(X_u)dK_u$, q.s. by Definition \\[increa\\].$\\square$\n\nIn the proof of classical It\u00f4\u2019s formula, (\\[conver1\\]) and (\\[conver2\\]) can be verified directly by the pathwise continuity of $X$ and the dominated convergence theorem on the product space $[s, t]\\times\\Omega$. But in $G$-framework, we are short of such a theorem. In general, given an $X\\in M^2_G([0, T])$, the sequence of step processes $\\{\\sum^{{2^N}-1}_{k=0}X_{t^{2^N}_k}I_{[t^{2^N}_k, t^{2^N}_{k+1})}(\\cdot)\\}_{N\\in\\mathbb{N}}$ could not converge to $X$ in the sense of $M^2_G([0, T])$. Thus, (\\[kconti\\]) is needed to ensure that (\\[hell\\]) holds true.\\\nIn fact, the left side of (\\[ITO\\]), particularly the term $\\int^t_s \\frac{d\\Phi}{dx}(X_u)dK_u$, still belongs to $L^2_G(\\Omega_t)$. A sufficient condition of this result is that $K_t\\in L^2_G(\\Omega_t)$, which can be verified by choosing a sequence such that $t_n\\rightarrow t$ and for $n\\in \\mathbb{N}$, $X_{t_n}\\in L^2_G(\\Omega_{t_n})$ (Remark \\[remconna\\] ensures the existence of this sequence), and by deducing from assumption $(\\ref{kconti})$.\n\nSimilar to Theorem 6.5 of Peng [@P3], we can extend $G$-It\u00f4\u2019s formula in Lemma \\[itolem\\] to those $\\Phi$ whose second derivates $\\frac{d^2\\Phi}{dx^2}$ has polynomial growth. Unfortunately, this extension is at a cost of more restriction on the increasing process $K$.\n\n\\[BT\\] Let $\\Phi\\in \\mathcal{C}^2(\\mathbb{R})$ be a real function such that $\\frac{d^2\\Phi}{dx^2}$ satisfies polynomial growth condition.

In what follows, we establish the solvability to the RGSDE of this type, i.e., the existence and uniqueness of the reflected $G$-Brownian Motion.\\\nLet $y$ be a real valued continuous function on $[0, T]$ with $y_0 \\geq 0$. It is well-known that, there exists a unique pair $(x, k)$ of functions on $[0, T]$ such that $x=y+k$, where $x$ is positive, $k$ is an increasing and continuous function starting from 0, moreover, the Riemann-Stieltjes integral $\\int^T_0 x_t dk_t = 0$.

The proof will be based on a Picard iteration.\n\nUnder the assumptions (A1)-(A4), there exists a unique solution in $M^p_G([0,T])$ to the RGSDE (\\[1\\]).\n\n**Proof:** We set $X^0=x$ and $K^0=0$. For each $n>0$, $X^{n+1}$ is given by recurrence: $$\\begin{aligned}\n\\label{picard}\n&X^{n+1}_t=x+\\int^t_0 f_s(X^n_s)ds+\\int^t_0 h_s(X^n_s)d\\langle B \\rangle_s +\\int^t_0 g_s(X^n_s) dB_s + K^{n+1}_t,\\ 0\\leq t\\leq T,\\end{aligned}$$ satisfying\\\n$\n\\begin{array}{l}\n(a)\\ X^{n+1}\\in M^p_G([0, T]),\\ X^{n+1}_t\\geq S_t,\\ q.s.;\\\\[6pt]\n(b)\\ K^{n+1}\\in M_I([0, T])\\cap M^p_G([0, T]),\\ K^{n+1}_0=0,\\ q.s.;\\\\[6pt]\n(c)\\ \\int^T_0(X_t^{n+1}-S_t)dK^{n+1}_t=0,\\ q.s..\n\\end{array}\n$\\\nSubstituting $X^{n+1}$ by $\\tilde{X}^{n+1}+S_t$ on the left side of (\\[picard\\]), we know that $(X^{n+1}, K^{n+1})$ is well defined in $M^p_G([0,T])\\times (M_I([0, T])\\cap M^p_G([0,T]))$ by Theorem \\[BXT\\].\\\nFirstly, we establish a priori estimates uniform in $n$ for $\\{\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|X^n_t|^p]\\}_{n\\in \\mathbb{N}}$. Similarly to (\\[est3\\]), we have $$\\begin{aligned}\n\\bar{\\mathbb{E}}[\\sup_{0\\leq s\\leq t}|X^{n+1}_t|^p]\n\\leq C\\bigg(|x|^p\n+&\\int^T_0 (\\bar{\\mathbb{E}}[|f_t(0)|^p]+\\bar{\\mathbb{E}}[|h_t(0)|^p]\\\\\n+&\\bar{\\mathbb{E}}[|g_t(0)|^p])dt\n+\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|S^+_t|^p]\n+\\int^t_0 \\bar{\\mathbb{E}}[\\sup_{0\\leq u\\leq s}|X^n_u|^p]ds\\bigg).\\end{aligned}$$ By recurrence, it is easily to verify that, for $n\\in\\mathbb{N}$, $$\\bar{\\mathbb{E}}[\\sup_{0\\leq s\\leq t}|X^n_s|^p]\\leq p(t),\\ 0\\leq t\\leq T,$$ where $p(\\cdot)$ is the solution to the following ordinary differential equation: $$p(t)=C\\bigg(|x|^p\n+\\int^T_0 (\\bar{\\mathbb{E}}[|f_t(0)|^p]+\\bar{\\mathbb{E}}[|h_t(0)|^p]\n+\\bar{\\mathbb{E}}[|g_t(0)|^p])dt\n+\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|S^+_t|^p]\n+\\int^t_0p(s)ds\\bigg),$$ and $p(\\cdot)$ is continuous and thus bounded on $[0, T]$.\\\nSecondly, for $n$ and $m\\in \\mathbb{N}$, we define $$u^{n+1,m}_t:=\\bar{\\mathbb{E}}[\\sup_{0\\leq s \\leq t}|X^{n+m+1}_s-X^{n+1}_s|^p],\\ 0\\leq t\\leq T.$$ Following the procedures in the proof of Theorem \\[345\\], we have $$u^{n+1,m}_t \\leq C\\int^t_0u^{n,m}_sds.$$ Set $$v^n_t := \\sup_{m\\in\\mathbb{N}} u^{n, m}_t,\\ 0\\leq t\\leq T,$$ then $$0\\leq u^{n+1, m}_t\\leq C\\sup_{m\\in\\mathbb{N}}\\int^t_0u^{n, m}_sds\\leq C\\int^t_0\\sup_{m\\in\\mathbb{N}}u^{n, m}_sds =C\\int^t_0 v^n_s ds.$$ Taking supremum on the left side, we obtain $$0\\leq v^{n+1}_t=\\sup_{m\\in\\mathbb{N}}u^{n+1,m}_t \\leq C\\int^t_0 v^n_s ds.$$ Finally, we define $$\\alpha_t := \\limsup_{k\\rightarrow+\\infty} v^n_t,\\ 0\\leq t\\leq T.\\notag$$ It is easy to find that $v^n_t \\leq Cp(t)$, where $C$ is independent of $n$. By classical Fatou\u2019s Lemma, we have $$0\\leq \\alpha_t \\leq C\\int^t_0 \\alpha_s ds.$$ Gronwall\u2019s lemma gives $$\\alpha_t=0,\\ 0\\leq t\\leq T,\\notag$$ which implies that $\\{X^n\\}_{n\\in\\mathbb{N}}$ is a Cauchy sequence in $M^p_G([0, T])$. We denote the limit by $X$ and set $$K_t=\\sup_{0\\leq s\\leq t}\\bigg( x+\\int^s_0 f_u(X_u)du+\\int^s_0 h_u(X_u)d\\langle B \\rangle_u +\\int^s_0 g_u(X_u) dB_u-S_s\\bigg)^-.$$ Obviously, the pair of processes $(X, K)$ satisfies (A5) - (A7). We notice that $$\\begin{aligned}\n&\\bar{\\mathbb{E}}\\bigg[\\sup_{0\\leq t\\leq T}\\bigg|\\int^t_0(f_s(X^n_s)-f_s(X_s))ds\\bigg|^p\\bigg]\\leq C\\int^T_0\\bar{\\mathbb{E}}[|X^n_t-X_t|^p]dt;\\\\\n&\\bar{\\mathbb{E}}\\bigg[\\sup_{0\\leq t\\leq T}\\bigg|\\int^t_0(h_s(X^n_s)-h_s(X_s))d\\langle B\\rangle_s\\bigg|^p\\bigg]\\leq C\\int^T_0\\bar{\\mathbb{E}}[|X^n_t-X_t|^p]dt;\\\\\n&\\bar{\\mathbb{E}}\\bigg[\\sup_{0\\leq t\\leq T}\\bigg|\\int^t_0(g_s(X^n_s)-g_s(X_s))dB_s\\bigg|^p\\bigg]\\leq C\\int^T_0\\bar{\\mathbb{E}}[|X^n_t-X_t|^p]dt.\\end{aligned}$$ Then, one can verify that $K^n$ converges to $K$ in $M^p_G([0, T])$ following the steps of (\\[est6\\]). We conclude that the pair of processes $(X,K)$, well defined in $M^p_G([0, T])\\times (M_I([0, T])\\cap M^p_G([0, T]))$, is a solution to (\\[1\\]).$\\square$\n\nUnlike in a classical RSDE, the constraint process $S$ here is assumed to be a $G$-It\u00f4 process instead of a continuous process with $\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}(S^+_t)^2]\\leq +\\infty$ (cf. El Karoui et al. [@EL]). In fact, this is a sufficient condition to ensure that $K^{n+1}$ is still a $M^p_G([0, T])$ process in (\\[picard\\]) by Theorem \\[BXT\\], which may be weakened to: $$\\bar{\\mathbb{E}}[\\sup_{s\\leq u\\leq t}|S_u-S_s|^p]\\leq C|t-s|^{\\frac{p}{2}}.$$\n\nUsing the approach in Soner et al. [@STZ2], this existence result still holds from a classical argument under each $\\mathbb{P}\\in\\mathcal{P}$, that is, a pair of process $(X^\\mathbb{P}, K^\\mathbb{P})$ can be found to satisfy (\\[1\\]) and (A5)-(A7) in the sense of $\\mathbb{P}$-a.s.. However, it is difficult to determine a universal $(X, K)$ which is the aggregation of these solutions $(X^\\mathbb{P}, K^\\mathbb{P})$, $\\mathbb{P}\\in\\mathcal{P}$.\n\nIn contrast with the fact mentioned in Remark 3.3 of Matoussi et al. [@MPZ], our results can be directly applied to the symmetrical problem i.e., the RGSDE with an upper barrier. This conclusion is due to the facts that the proof is only based on a pathwise construction and a fixed-point iteration.\n\nComparison principle\n--------------------\n\nIn this subsection, we establish a comparison principle for RGSDEs. At first, we assume additionally a bounded condition on the coefficients $f$, $h$ and $g$ and the obstacle process $S$, and then we remove it in the second step.\n\n\\[CT\\] Given two RGSDEs satisfying the conditions (A1)-(A4), we suppose in addition the following:\n\n$x^1\\leq x^2$;\n\n$f^i$, $h^i$ and $g^1=g^2=g$ are bounded, and $S^i$ are uniformly upper bounded, $i=1, 2$;\n\n$f^1_t(x)\\leq f^2_t(x)$ and $h^1_t(x)\\leq h^2_t(x)$, for $x\\in\\mathbb{R}$, and $S^1_t\\leq S^2_t$, $0\\leq t\\leq T$, q.s..\n\nLet $(X^i, K^i)$ be a pair of solutions to the RGSDEs with data $(f^i, h^i, g, S^i)$, $i=1, 2$, then, $$X^1_t\\leq X^2_t,\\ 0\\leq t\\leq T,\\ q.s..$$\n\n**Proof:** Since $f^i$, $h^i$ and $g$ are bounded, and $S^i$ are uniformly upper bounded, $i=1, 2$, using the BDG type inequalities to (\\[represen\\]), we deduce that $K^i_T$ has the moment for arbitrage large order and for $0\\leq t\\leq T$, $\\lim_{s\\rightarrow t}\\bar{\\mathbb{E}}[|K^i_t-K^i_s|^2]=0$, $i=1, 2$.\\\nNotice that $(x^+)^2$ is not a $\\mathcal{C}^2(\\mathbb{R})$ function, we have to consider $(x^+)^3$ and apply the extended $G$-It\u00f4\u2019s formula to $((X^1_t-X^2_t)^+)^3$, $$\\begin{aligned}\n\\label{cal1}\n((X^1_t-X^2_t)^+)^3\n=&3\\int^t_0|(X^1_s-X^2_s)^+|^2(f^1_s(X^1_s)-f^2_s(X^2_s))ds\\notag\\\\\n+&3\\int^t_0|(X^1_s-X^2_s)^+|^2(h^1_s(X^1_s)-h^2_s(X^2_s))d\\langle B\\rangle_s\\notag\\\\\n+&3\\int^t_0|(X^1_s-X^2_s)^+|^2(g_s(X^1_s)-g_s(X^2_s))dB_s\\\\\n+&3\\int^t_0|(X^1_s-X^2_s)^+|^2d(K^1_s-K^2_s)\\notag\\\\\n+&3\\int^t_0(X^1_s-X^2_s)^+|g_s(X^1_s)-g_s(X^2_s)|^2 d\\langle B\\rangle_s.\\notag\\end{aligned}$$ Since on $\\{X^1_t>X^2_t\\}$, $X^1_t>X^2_t\\geq S^2_t\\geq S^1_t$, we have $$\\begin{aligned}\n\\label{cal2}\n\\int^t_0|(X^1_s-X^2_s)^+|^2d(K^1_s-K^2_s)&=\\int^t_0|(X^1_s-X^2_s)^+|^2dK^1_s-\n\\int^t_0|(X^1_s-X^2_s)^+|^2dK^2_s\\notag\\\\\n&\\leq \\int^t_0|(X^1_s-S^1_s)^+|^2dK^1_s-\n\\int^t_0|(X^1_s-X^2_s)^+|^2dK^2_s\\\\\n&\\leq -\n\\int^t_0|(X^1_s-X^2_s)^+|^2dK^2_s\\leq 0,\\ q.s..\\notag\\end{aligned}$$ We put (\\[cal2\\]) into (\\[cal1\\]). Then, by Lipschitz condition (A3) and taking $G$-expectation on both sides of (\\[cal2\\]), we conclude $$\\begin{aligned}\n\\label{complex}\n\\bar{\\mathbb{E}}[((X^1_t-X^2_t)^+)^3]\\leq C\\bar{\\mathbb{E}}\\bigg[\\int^t_0((X^1_s-X^2_s)^+)^3ds\\bigg]\\leq C\\int^t_0\\bar{\\mathbb{E}}[((X^1_s-X^2_s)^+)^3]ds.\\end{aligned}$$ Using Gronwall\u2019s lemma, it follows that $\\bar{\\mathbb{E}}[((X^1_t-X^2_t)^+)^3]=0$, which implies the result.$\\square$.\n\nGiven two RGSDEs satisfying the conditions (A1)-(A4), and suppose in addition the following:\n\n$x^1\\leq x^2$ and $g^1=g^2=g$;\n\n$f^1_t(x)\\leq f^2_t(x)$ and $h^1_t(x)\\leq h^2_t(x)$, for $x\\in\\mathbb{R}$, and $S^1_t\\leq S^2_t$, $0\\leq t\\leq T$, q.s..\n\nLet $(X^1,K^1)$ and $(X^2, K^2)$ are two pairs of solutions to the RGSDEs above, then, $$X^1_t\\leq X^2_t,\\ 0\\leq t\\leq T,\\ q.s..$$\n\n**Proof:** Firstly, we define the truncation functions for the coefficients and the obstacle process: for $N>0$, $\\xi^N_t(x)=(-N\\vee \\xi_t(x))\\wedge N$, $x\\in\\mathbb{R}$, where $\\xi$ denote $f^i$, $h^i$ and $g$, $i=1, 2$, and $S^N_t=S_t\\wedge N$, $0\\leq t\\leq T$. It is easy to verify that the truncated coefficients and obstacle processes satisfy (A2) and (A3). Moreover, the truncation functions keep the order of the coefficients and obstacle processes, that is, $$(f^1)^N_t(x)\\leq (f^2)^N_t(x),\\ (h^1)^N_t(x)\\leq (h^2)^N_t(x)\\ and\\ (S^1)^N_t \\leq (S^2)^N_t,\\ 0\\leq t\\leq T,\\ q.s..$$ Consider the following RGSDEs on $[0, T]$, for $i=1, 2$, $$\\begin{aligned}\n(X^i)^N_t=x+\\int^t_0 (f^i)^N_s((X^i)^N_s)ds+\\int^t_0 (h^i)^N_s((X^i)^N_s)d\\langle B \\rangle_s +\\int^t_0 g^N_s((X^i)^N_s) dB_s + (K^i)^N_t;\\end{aligned}$$ satisfies\\\n$\n\\begin{array}{l}\n(a)\\ (X^i)^N_t\\in M^p_G([0, T]),\\ (X^i)^{N}_t\\geq (S^i)^N_t,\\ q.s.;\\\\[6pt]\n(b)\\ (K^i)^N\\in M_I([0, T])\\cap M^p_G([0, T]),\\ (K^i)^N_0=0,\\ q.s.;\\\\[6pt]\n(c)\\ \\int^T_0((X^i)^N_t-(S^i)^N_t)d(K^i)^{N}_t=0,\\ q.s..\n\\end{array}\n$\\\nBy Theorem \\[CT\\], we have $$\\label{last}\n(X^1)^N_t\\leq (X^2)^N_t,\\ q.s..$$ Meanwhile, by Theorem \\[345\\], we have $$\\begin{array}{r@{\\ }l}\n\\bar{\\mathbb{E}}[\\sup_{0\\leq s\\leq t}|(X^i)^N_s-X^i_s|^p]\n\\leq&C(\\int^T_0(\n\\bar{\\mathbb{E}}[|(f^i)^N_t(X^i_t)-f^i_t(X^i_t)|^p]+\\bar{\\mathbb{E}}[|(h^i)^N_t(X^i_t)-h^i_t(X^i_t)|^p]\\\\[6pt]\n+&\\bar{\\mathbb{E}}[|g^N_t(X^i_t)-g_t(X^i_t)|^p]\n)dt+\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(S^i)^N_t-S^i_t|^p]\\\\[6pt]\n+&\\int^t_0\\bar{\\mathbb{E}}[\\sup_{0\\leq u\\leq s}|(X^i)^N_u-X^i_u|^p]ds).\n\\end{array}$$ Applying again Gronwall\u2019s lemma, we obtain $$\\begin{aligned}\n\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(X^i)^N_t-X^i_t|^p]\n\\leq& C\\bigg(\\int^T_0(\n\\bar{\\mathbb{E}}[|(f^i)^N(t, X^i_t)-f^i(t, X^i_t)|^p]+\\bar{\\mathbb{E}}[|(h^i)^N(t, X^i_t)-h^i(t, X^i_t)|^p]\\\\\n+&\\bar{\\mathbb{E}}[|g^N(t, X^i_t)-g(t, X^i_t)|^p]\n)dt+\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(S^i)^N_t-S^i_t|^p]\\bigg).\\end{aligned}$$ For any $t\\in[0, T]$, we calculate $$\\begin{aligned}\n\\bar{\\mathbb{E}}[|(f^i)^N_t(X^i_t)-f^i_t(X^i_t)|^p]\\leq& \\bar{\\mathbb{E}}[|f^i_t(X^i_t)|^pI_{|f^i_t(X^i_t)|>N}]\\\\\n\\leq& \\bar{\\mathbb{E}}[(|f^i_t(0)|+C_L|X^i_t|)^pI_{(|f^i_t(0)|+C_L|X^i_t|)>N}]\\\\\n\\leq& C(\\bar{\\mathbb{E}}[|f^i_t(0)|^pI_{|f^i_t(0)|>\\frac{N}{2}}]+\\bar{\\mathbb{E}}[|X^i_t|^pI_{|X^i_t|>\\frac{N}{2}}]).\\end{aligned}$$ Taking into consideration that $f_\\cdot(0)$ and $X^i\\in M^p_G([0, T])$, from the argument in Remark \\[remconna\\], we know that $f_t(0)$ and $X^i_t\\in L^p_G([0, T])$ for almost every $t\\in[0, T]$. Therefore, letting $N\\rightarrow +\\infty$, we have $$\\bar{\\mathbb{E}}[|(f^i)^N_t(X^i_t)-f^i_t(X^i_t)|^p]\\rightarrow 0.$$ Similarly, we can obtain that $$\\bar{\\mathbb{E}}[|(h^i)^N_t(X^i_t)-h^i_t(X^i_t)|^p]\\rightarrow 0\n;$$ and $$\\bar{\\mathbb{E}}[|(g^i)^N_t(X^i_t)-g^i_t(X^i_t)|^p]\\rightarrow 0.$$ Using dominated convergence theorem to the integrals on $[0, T]$, it follows that $$\\begin{aligned}\n\\label{cal3}\n\\lim_{N\\rightarrow +\\infty}\n\\int^T_0(\\bar{\\mathbb{E}}[|(f^i)^N(t, X^i_t)-f^i(t, X^i_t)|^p]+\\bar{\\mathbb{E}}[|(h^i)^N(t, X^i_t)-&h^i(t, X^i_t)|^p]\\\\\n+&\\bar{\\mathbb{E}}[|g^N(t, X^i_t)-g(t, X^i_t)|^p]\n)dt=0.\\notag\\end{aligned}$$ On the other hand, $$\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(S^i)^N_t-S^i_t|^p]\\leq \\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}(|S^i_t|^pI_{\\{|S^i_t|>N\\}})]\\leq \\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|S^i_t|^pI_{\\{\\sup_{0\\leq t\\leq T}|S^i_t|>N\\}}].$$ By the proof of Theorem \\[BXT\\], we know that $\\sup_{0\\leq t\\leq T}S^i_t$ is an element in $L^p_G(\\Omega_T)$. So we have $$\\begin{aligned}\n\\label{cal4}\n\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(S^i)^N_t-S^i_t|^p]\\leq \\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|S^i_t|^pI_{\\{\\sup_{0\\leq t\\leq T}|S^i_t|>N\\}}]\\rightarrow 0,\\ as\\ N\\rightarrow +\\infty.\\end{aligned}$$ Combining (\\[cal3\\]) and (\\[cal4\\]), we obtain $$\\label{last2}\n\\bar{\\mathbb{E}}[\\sup_{0\\leq t\\leq T}|(X^i)^N_t-X^i_t|^p]\\rightarrow 0,\\ as\\ N\\rightarrow +\\infty.$$ Then, (\\[last\\]) and (\\[last2\\]) yield the desired result .$\\square$\\\n**Acknowledgement**\u00a0The author expresses special thanks to Prof. , who provided both the initial inspiration for the work and useful suggestions, and also to the anonymous reviewers, who have given me a lot of important constructive advice for the revision.\n\n[10]{}\n\nLin Y., Bai, X., On the existence and uniqueness of solutions to stochastic differential equations driven by $G$-Brownian motion with integral-Lipschitz coefficients, arXiv:1002.1046v4.
