随机快扩散方程的Harnack不等式和强Feller性质

Harnack Inequality and Strong Feller Property for Stochastic Fast-Diffusion Equations

Wei Liu, Feng-Yu Wang

摘要:

本文对随机快扩散方程给出了类似的结果。由于快扩散方程的耗散性弱于多孔介质方程,这给研究带来了一些技术上的困难。作为对较弱耗散性条件的补偿,在应用中对基本的自伴算子假设一个Sobolev-Nash不等式.构造了一些具体的例子来说明主要结果。

英文摘要:

This paper presents analogous results for stochastic fast-diffusion equations. Since the fast-diffusion equation possesses weaker dissipativity than the porous medium one does, some technical difficulties appear in the study. As a compensation to the weaker dissipativity condition, a Sobolev-Nash inequality is assumed for the underlying self-adjoint operator in applications. Some concrete examples are constructed to illustrate the main results.
