Abstract

Let G be an additive finite abelian group with exponent exp(G). Let s(G) (resp. @h(G)) be the smallest integer t such that every sequence of t elements (repetition allowed) from G contains a zero-sum subsequence T of length |T|=exp(G) (resp. |T|@?[1,exp(G)]). Let H be an arbitrary finite abelian group with exp(H)=m. In this paper, we show that s(C"m"n@?H)=@h(C"m"n@?H)+mn-1 holds for all n=max{m|H|+1,4|H|+2m}.
