具有Neumann边界条件的抛物型方程的黏性解的大时间性态的概率方法

A probabilistic approach to large time behaviour of viscosity solutions of parabolic equations with Neumann boundary conditions

Ying Hu, Pierre-Yves Madec

摘要:

本文研究了具有Neumann边界条件的抛物型方程的黏性解的长时间性态。本文是文[13]的续篇,文[13]用概率方法证明了抛物型半线性偏微分方程的解类似于线性项$λT$随函数$v$移位,其中$(v,λ)$是与抛物型偏微分方程相关的遍历偏微分方程的解.我们适应这种方法在有限维的惩罚方法,以便能够应用一个重要的基本耦合估计结果和正则化过程的帮助下,以避免缺乏规律性的系数在有限维。我们的方法的优点是,它给出了一个明确的收敛速率。

英文摘要:

This paper is devoted to the study of the large time behaviour of viscosity solutions of parabolic equations with Neumann boundary conditions. This work is the sequel of [13] in which a probabilistic method was developped to show that the solution of a parabolic semilinear PDE behaves like a linear term $λT$ shifted with a function $v$, where $(v,λ)$ is the solution of the ergodic PDE associated to the parabolic PDE. We adapt this method in finite dimension by a penalization method in order to be able to apply an important basic coupling estimate result and with the help of a regularization procedure in order to avoid the lack of regularity of the coefficients in finite dimension. The advantage of our method is that it gives an explicit rate of convergence.
