关于扩散过程的亚几何遍历性

On Sub-Geometric Ergodicity of Diffusion Processes

Petra Lazić, Nikola Sandrić

摘要:

本文讨论由伊藤随机微分方程给出的扩散过程的遍历性。我们确定的漂移和扩散系数的条件,导致在相应的半群的子几何遍历相对于全变差距离。在一类Wasserstein距离下证明了半群的次几何压缩性和遍历性。最后讨论了两类带跳马氏过程的次几何遍历性。

英文摘要:

In this article, we discuss ergodicity properties of a diffusion process given through an Itô stochastic differential equation. We identify conditions on the drift and diffusion coefficients which result in sub-geometric ergodicity of the corresponding semigroup with respect to the total variation distance. We also prove sub-geometric contractivity and ergodicity of the semigroup under a class of Wasserstein distances. Finally, we discuss sub-geometric ergodicity of two classes of Markov processes with jumps.
