具有任意阶导数的完全非线性Feynman-Kac公式

A fully nonlinear Feynman-Kac formula with derivatives of arbitrary orders

Jiang Yu Nguwi, Guillaume Penent, Nicolas Privault

摘要:

本文提出了一种求解非线性抛物型偏微分方程的数值算法。该算法利用随机树的分支上携带的非线性信息,将经典的Feynman-Kac公式推广到完全非线性偏微分方程。它适用于不被标准分支参数处理的函数的非多项式非线性,并处理任意阶的导数项。一个蒙特卡罗数值实现。

英文摘要:

We present an algorithm for the numerical solution of nonlinear parabolic partial differential equations. This algorithm extends the classical Feynman-Kac formula to fully nonlinear partial differential equations, by using random trees that carry information on nonlinearities on their branches. It applies to functional, non-polynomial nonlinearities that are not treated by standard branching arguments, and deals with derivative terms of arbitrary orders. A Monte Carlo numerical implementation is provided.
