Let G be an additive finite abelian group with exponent n. Let D (G) be the Davenport constant of G, s k n (G) the k th Erdős–Ginzburg–Ziv constant of G, where k is a positive integer. Recently, Gao, Han, Peng and Sun conjectured that s k n (G)= k n+ D (G)− 1 holds if k≥⌈ D (G) n⌉. Let m, n be positive integers and H an abelian p-group with D (H)≤ p n. Let G= H⊕ C m p n. For any integer k≥ 2, we prove that s k m p n (G)=(k+ 1) m p n+ D (H)− 2= k m p n+ D (G)− 1. This verifies the above conjecture in this case. We also provide asymptotically tight bounds for zero-sum invariants D (G), s k n (G) and η (G) for a class of abelian groups with large exponent.
