Log-Harnack Inequalities for Markov Semigroups Generated by Non-Local Gruschin Type Operators

Abstract

Based on coupling in two steps and the regularization approximations of the underlying subordinators, we establish log-Harnack inequalities for Markov semigroups generated by a class of non-local Gruschin type operators. Some concrete examples are also presented.
