Ergodicity for Time Changed Symmetric Stable Processes
arXiv:1312.5042
Abstract
In this paper we study the ergodicity and the related semigroup property for a class of symmetric Markov jump processes associated with time changed symmetric -stable processes. For this purpose, explicit and sharp criteria for Poincaré type inequalities (including Poincaré, super Poincaré and weak Poincaré inequalities) of the corresponding non-local Dirichlet forms are derived. Moreover, our main results, when applied to a class of one-dimensional stochastic differential equations driven by symmetric -stable processes, yield sharp criteria for their various ergodic properties and corresponding functional inequalities.
