A Lyapunov Bound for Solutions of Poisson's Equation
Abstract
Suppose that X is a positive recurrent Harris chain with invariant measure pi. We develop a Lyapunov function criterion that permits one to bound the solution g to Poisson's equation for X. This bound is then applied to obtain sufficient conditions that guarantee that the solution be an element of L sub p (pi). When p = 2, the square integrability of g implies the validity of a functional central limit theorem for the Markov chain. We illustrate the technique with applications to the waiting time sequence of the single-server queue and autoregressive sequences. Keywords: Functional central limit theorem.
