报告摘要 Abstract:

Let G be an additive finite abelian group. Let B(G) denote the set of all zero-sum sequences over G. For A ⊆ B(G), let d_A(G) be the smallest integer t such that every sequence S over G of length |S|≥t has a subsequence in A. In 2018, d_A(G) was first formulated by Gao, Li, Peng and Wang to give a unifying look at zero-sum invariants on finite abelian groups. In this talk, we shall present some recent new results on d_A(G) and we also present some open problems related to d_A(G).
