A note on Furstenberg's filtering problem

Probability 2009-06-13 v3 Dynamical Systems

Abstract

This short note gives a positive answer to an old question in elementary probability theory that arose in Furstenberg's seminal article "Disjointness in Ergodic Theory." As a consequence, Furstenberg's filtering theorem holds without any integrability assumption.
