The ErdÅs-Ginzburg-Ziv theorem constant of finite groups

Yang Zhao, Guoqing Wang

Let $G$ be a multiplicatively written finite group of order $n$ . The ErdÅs-Ginzburg-Ziv Theorem constant of the group $G$ , denoted $E (G)$ , is defined as the smallest posit…

Semigroup rings and algebraically independent sequences with respect to idempotents in commutative semigroups

Guoqing Wang

For any finite abelian group $G$ and commutative unitary ring $R$ , by $R [G]$ we denote the group algebra over $R$ . Let $T = (g_{1}, \dots, g_{ℓ})$ be a sequence over the group $G$ . W…

Enumeration of idempotent-sum subsequences in finite cyclic semigroups and smooth sequences

Guoqing Wang, Yang Zhao, Xingliang Yi

The enumeration of zero-sum subsequences of a given sequence over finite cyclic groups is one classical topic, which starts from one question of P. ErdÅs. In this paper, we consid…

On Bass' conjecture of the small Davenport constant

Guoqing Wang, Yang Zhao

Let $G$ be a finite group. The small Davenport constant $d (G)$ of $G$ is the maximal integer $ℓ$ such that there is a sequence of length $ℓ$ over $G$ which has no non…
