对称稳定Lévy过程的弱Harnack不等式和Hölder正则性

Weak Harnack Inequality and Hölder Regularity for Symmetric Stable Lévy Processes

Marina Sertic

摘要:

本文考虑对称$α$ -稳定Lévy过程在$\mathbb{R}^d$,$α\in (0,2)$,$d\geq 2$中的弱Harnack不等式和Hölder正则性估计.考虑对称$α$ -稳定Lévy过程$X$,其中Lévy测度的球面部分$μ$是谱测度.另外,我们假设$μ$关于球面上的一致测度$σ$是绝对连续的,并对相应的密度施加一定的界限.最后,我们证明了弱Harnack不等式成立,我们应用它来证明Hölder正则性结果。

英文摘要:

In this paper we consider weak Harnack inequality and Hölder regularity estimates for symmetric $α$-stable Lévy process in $\mathbb{R}^d$, $α\in (0,2)$, $d\geq 2$. We consider a symmetric $α$-stable Lévy process $X$ for which a spherical part $μ$ of the Lévy measure is a spectral measure. In addition, we assume that $μ$ is absolutely continuous with respect to the uniform measure $σ$ on the sphere and impose certain bounds on the corresponding density. Eventually, we show that the weak Harnack inequality holds, which we apply to prove Hölder regularity results.
