倒向双重随机微分方程的数值格式

Numerical scheme for backward doubly stochastic differential equations

Auguste Aman

摘要:

研究了解耦正倒向双随机微分方程(FBDSDEs)解的离散时间逼近。假设系数是Lipschitz连续的,我们证明了当时间离散步长$|π|$趋于零时格式的收敛性。收敛速率正好等于$|π|^{1/2}$。这个证明是基于J. Zhang关于向后方程解的$^{2}$ -正则性的一个显著结果的推广

英文摘要:

We study a discrete-time approximation for solutions of systems of decoupled forward-backward doubly stochastic differential equations (FBDSDEs). Assuming that the coefficients are Lipschitz-continuous, we prove the convergence of the scheme when the step of time discretization, $|π|$ goes to zero. The rate of convergence is exactly equal to $|π|^{1/2}$. The proof is based on a generalization of a remarkable result on the $^{2}$-regularity of the solution of the backward equation derived by J. Zhang
