Erdős-Ginzburg-Ziv theorem for finite commutative semigroups

Sukumar Das Adhikari, Weidong Gao, Guoqing Wang

Let $S$ be a finite commutative semigroup written additively, and let $exp (S)$ be its exponent which is defined as the least common multiple of all periods of…

On n-sum of an abelian group of order n

Xingwu Xia, Weidong Gao

Let $G$ be an additive finite abelian group of order $n$ , and let $S$ be a sequence of $n + k$ elements in $G$ , where $k \geq 1$ . Suppose that $S$ contains $t$ distinct elements. Let…

An upper bound for Davenport constant of finite groups

Weidong Gao, Yuanlin Li, Jiangtao Peng

Let $G$ be a finite (not necessarily abelian) group and let $p = p (G)$ be the smallest prime number dividing $∣ G ∣$ . We prove that $d (G) \leq \frac{∣ G ∣}{p} + 9 p^{2} - 10 p$ , where $d (G)$ deno…

Local and global tameness in Krull monoids

W. D. Gao, Alfred Geroldinger, Wolfgang Schmid

Let H be a Krull monoid with finite class group G such that every class contains a prime divisor. Then the global tame degree t (H) equals zero if and only if H is factorial (equiv…
