 应甘肃省数学与统计学基础学科研究中心邀请,广东工业大学乔守红教授将为学院师生作学术报告。

报告题目:Subgroup perfect codes of finite groups

报告摘要:A perfect code C in a graph X is an independent set of X such that every vertex of X outside C is adjacent to exactly one vertex in C. A subgroup perfect code in a finite group G is a subgroup H that can be realized as a perfect code in a Cayley graph of G. In this talk, we will show that subgroup perfect codes can be characterized by the "local" complements and discuss the influences of subgroup perfect codes on the structure of 2-groups. We also investigate the core-free maximal subgroups of primitive groups G. Finally, we will present some applications of these results to linear groups and symmetrical groups. It is a joint work with N. Su, B. Xia, Z. Zhang and S. Zhou.
