On short zero-sum subsequences of zero-sum sequences

Yushuang Fan, Weidong Gao, Guoqing Wang +2

Let $G$ be a finite abelian group, and let $η (G)$ be the smallest integer $d$ such that every sequence over $G$ of length at least $d$ contains a zero-sum subsequence $T$ with leng…

Congruences on the Bell polynomials and the derangement polynomials

Yidong Sun, Xiaojuan Wu, Jujuan Zhuang

In this note, by the umbra calculus method, the Sun and Zagier's congruences involving the Bell numbers and the derangement numbers are generalized to the polynomial cases. Some sp…

$λ$ -factorials of $n$

Yidong Sun, Jujuan Zhuang

Recently, by the Riordan's identity related to tree enumerations, \begin{eqnarray*} \sum_{k=0}^{n}\binom{n}{k}(k+1)!(n+1)^{n-k} &=& (n+1)^{n+1}, \end{eqnarray*} Sun and Xu derived…

Weighted Sequences in Finite Cyclic Groups

David J. Grynkiewicz, Jujuan Zhuang

Let $p > 7$ be a prime, let $G = Z / p Z$ , and let $S_{1} = \prod_{i = 1}^{p} g_{i}$ and $S_{2} = \prod_{i = 1}^{p} h_{i}$ be two sequences with terms from $G$ . Suppose that the maximum multiplicity of a t…
