Martingale approximation of non-stationary stochastic processes

Probability 2023-11-07 v1

Abstract

We generalise the martingale-coboundary representation of discrete time stochastic processes to the non-stationary case and to random variables in Orlicz spaces. Related limit theorems (CLT, invariance principle, log log law, probabilities of large deviations) are studied.
