群与图讨论班 Seminars on Groups and Graphs

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: Unoriented Regular Cayley Maps of Elementary abelian \(p\)-groups

Speaker: 于浩 Hao Yu (Captial Normal University)

Time: 16:00-17:00 (GMT+8), Wednesday April 24th

Location: Zoom: 616 601 4311 (passcode: gts2024)

Abstract: Recently, orientable regular Cayley maps of elementary abelian \(p\)-groups \(\mathbb{Z}_p^n\) are classified. A nature question is to classify nonorientably regular Cayley maps of \(\mathbb{Z}_p^n\). In this talk, we shall give a complete classification of them and moreover, the relationship between oriented maps and nonoriented maps is also studied.
