这是群论和图论方向的线上系列报告，我们希望能够促进国内外青年学者（博士生为主）在群论和图论研究上的交流。报告主题分布在（但不限于）以下研究方向：
- - 有限单群（有限单群分类定理，子群结构，共轭类等）
- - 置换群及其在组合结构上的作用
- - 线性代数群与李型群
- - 有限群的表示
- - 有限\(p\)-群
- - 图的谱理论
This is a platform for young group theorists and graph theorists (mostly PhD students) to talk about their research and related topics online.
The topic can be anything related to group theory and graph theory, including but not limited to the following.
- - Finite simple groups (CFSG, subgroup structures and conjugacy classes)
- - Permutation groups and their actions on combinatorial structures
- - Linear algebraic groups and Lie type groups
- - Representations of finite groups
- - Finite \(p\)-groups
- - Spectral theory of graphs
Time
一般地，系列报告定期于北京时间每周三下午16:00-17:00进行。
Our usual time is Wednesday 16:00-17:00 (GMT+8).

The Next Seminar
Title: A new characterization of \(E_8(p)\) via its vanishing elements
Speaker: 张晟民 Shengmin Zhang (China Agricultural University)
Time: 16:00-17:00 (GMT+8), Wednesday February 26th
Location: Tencent Meeting: 142-775-152 (passcode: 2025)
Abstract:
In this talk, we give a brief overview to the characterizations of simple groups via their vanishing elements,
and explain how vanishing elements influence the structure of simple groups. We will discuss
a new characterization of \(E_8 (p)\) via its vanishing elements when \(p\) is congruent to \(0,1,4\) modulo \(5\).
