摘要:We establish a monotone approximation scheme for Peng's G-equation and, moreover, determine the convergence rate by obtaining the error bounds between the approximate solution and the viscosity solution of the G-equation. This will in turn provides a convergence rate for Peng's central limit theorem. The convergence rate improves all the existing ones obtained under different model assumptions in the literature. Our method is analytical and is developed under the framework of the numerical analysis of viscosity solutions. Hence, it also makes an intrinsic connection between the robust central limit theorem and monotone schemes for viscosity solutions. Joint work with Shuo Huang.
