On Central Limit Theorems for Additive Functionals of Reversible Ergodic Markov Processes

Abstract

In this note, the time reversible case of a general theorem of Bhattacharya is shown to imply the Kipnis-Varadhan functional central limit theorem for ergodic Markov processes. To this end, a few results from semigroup theory, including the resolvent identity, are incoporated in Bhattacharya's range condition for the inifinitesimal generator.

This is a replacement in which an application of the method has been added to obtain an extended law of the iterated logarithm
