Finite covers of groups by cosets or subgroups

Zhi-Wei Sun

This paper deals with combinatorial aspects of finite covers of groups by cosets or subgroups. Let $a_{1} G_{1}, ..., a_{k} G_{k}$ be left cosets in a group $G$ such that $a_{i} G_{i}_{i = 1}^{k}$ co…

Groups and Combinatorial Number Theory

Zhi-Wei Sun

In this talk we introduce several topics in combinatorial number theory which are related to groups; the topics include combinatorial aspects of covers of groups by cosets, and als…

On the Herzog-Schönheim conjecture for uniform covers of groups

Zhi-Wei Sun

Let G be any group and $a_{1} G_{1}, ..., a_{k} G_{k} (k > 1)$ be left cosets in G. In 1974 Herzog and Schönheim conjectured that if $\Cal A=\{a_iG_i\}_{i=1}^k$ is a partition of G then the (fin…
