On the measure concentration of infinitely divisible distributions

Jing Zhang, Ze-Chun Hu, Wei Sun

Let $I$ be the set of all infinitely divisible random variables\ with finite second moments, $I_{0} = {X \in I : Var (X) > 0}$ , $P_{\cal I}=\inf_{X\in{\cal I}}P\{…

A system of nonlinear equations with application to large deviations for Markov chains with finite lifetime

Ze-Chun Hu, Wei Sun, Jing Zhang

In this paper, we first show the existence of solutions to the following system of nonlinear equations \begin{eqnarray*}\left\{\begin{array}{l} a_{11}x_1+a_{12}x_2+a_{13}x_3+\cdots…

Levy-Khintchine type representation of Dirichlet generators and Semi-Dirichlet forms

Wei Sun, Jing Zhang

Let $U$ be an open set of $R^{n}$ , $m$ a positive Radon measure on $U$ such that $supp [m] = U$ , and $(P_{t})_{t > 0}$ a strongly continuous contraction sub-Markovian semigro…
