非线性单调SPDES的反射渐近耦合及其应用

Asymptotic Couplings by Reflection and Applications for Non-Linear Monotone SPDES

Feng-Yu Wang

摘要:

构造了一类非线性单调随机偏微分方程的反射渐近耦合。作为应用,得到了相应的马尔可夫半群的梯度/Hölder估计和指数收敛性.主要结果用随机广义多孔介质方程、随机$p$ -Laplacian方程和随机广义快速扩散方程来说明。本文首次研究了这类方程的梯度估计。

英文摘要:

Asymptotic couplings by reflection are constructed for a class of non-linear monotone SPDES (stochastic partial differential equations). As applications, the gradient/Hölder estimates as well as the exponential convergence are derived for the associated Markov semigroup. The main results are illustrated by stochastic generalized porous media equations, stochastic $p$-Laplacian equations, and stochastic generalized fast-diffusion equations. We emphasize that the gradient estimate is studied at the first time for these equations.
