Abstract

In this paper we will systematically study the preservation of the notion of largeness of sets, arises from the algebraic structure of Stone-Cech compactification, under homomorphism and difference group. Some of these results were studied previously using algebra of Stone-Cech compactification. But our approach is purely combinatorial.
