Abstract: | Let X be a compact space,µ a Borel probability measureon X, T: X X a measure preserving continuous transformationand g: X R a continuous function. Then for some yX,
This Lemma is used to give an alternative proof of a resultby Ruzsa 6], which implies the following extension of a resultof Bergelson 1]. If E N satisfies
then there exists a set N such that n1|1,n]| (E) for all, n 1, and any finite subset{1, ... k} satisfies Ø.
