Log-Harnack Inequality for Gruschin Type Semigroups

Probability 2012-06-05 v1

Abstract

By constructing a coupling in two steps and using the Girsanov theorem under a regular conditional probability, the log-Harnack inequality is established for a large class of Gruschin type semigroups whose generator might be both degenerate and non-Lipschitzian.
