ON SUBSEQUENCE SUMS OF ZERO-SUM FREE SEQUENCES IN ABELIAN GROUPS OF RANK TWO
Let with and S be a sequence with elements of G. Let denote the set of group elements which can be expressed as a sum of a nonempty subsequence of S. Let denote the Davenport constant of G. In this paper, we show that if S contains elements of G, then either or Moreover, we determine the structure of the sequence S with length such that and
