Large and small sets with respect to homomorphisms and products of groups
Keywords:Group, Large set, Small set, P-small set, Homomorphism, Direct product
AbstractWe study the behaviour of large, small and medium subsets with respect to homomorphisms and products of groups. Then we introduce the definition af a P-small set in abelian groups and we investigate the relations between this kind of smallness and the previous one, giving some examples that distinguish them.
