摘要:We establish a monotone approximation scheme forPeng's G-equation and, moreover, determine the convergence rate byobtaining the error bounds between the approximate solution and the viscositysolution of the G-equation. This will in turn provides a convergence rate forPeng's central limit theorem. The convergence rate improves all theexisting ones obtained under different model assumptions in theliterature. Our method is analytical and is developed under the frameworkof the numerical analysis of viscosity solutions. Hence, it also makes anintrinsic connection between the robust central limit theorem and monotoneschemes for viscosity solutions. Joint work with Shuo Huang.
