On hitting time distributions of Markov processes with sub-Gaussian heat kernel bounds

Liping Li, Shuwen Lou

In this paper, we study the hitting times of Borel right processes on a metric measure space whose heat kernels satisfy sub-Gaussian bounds. It is well known that if $X=(…

Representations over diagrams of abelian categories II: Abelian model structures

Zhenxing Di, Liping Li, Li Liang +1

This is the second paper in a series on representations over diagrams of abelian categories. We show that, under certain conditions, a compatible family of abelian model categories…

On the restriction of a right process outside a negligible set

Liping Li, Michael Röckner

The objective of this paper is to examine the restriction of a right process on a Radon topological space, excluding a negligible set, and investigate whether the restricted object…

Dirichlet form approach to diffusions with discontinuous scale

Liping Li

It is well known that a regular diffusion on an interval without killing inside is uniquely determined by a canonical scale function and a canonical speed measure . Note…

On generalization of quasidiffusions

Liping Li

A quasidiffusion is by definition a time-changed Brownian motion on certain closed subset of . The aim of this paper is two-fold. On one hand, we will put forward a gen…
