# Prime graphs and actions of primitive groups

## Melissa Lee

University of Auckland

Time: 16:00-18:00 (GMT+8), Thursday June 9th, 2022
Location: Tencent Meeting

Abstract: I will be discussing a number of problems related to properties of finite groups that have piqued my interest over the past couple of years. Many involve bases of permutation groups $$G\leqslant\mathrm{Sym}(\Omega)$$, which are subsets $$B\subseteq\Omega$$ with trivial pointwise stabiliser. There will also be a few open problems along the way.

This seminar was mainly advertised by SUSTech International Center for Mathematics for its Algebra and Discrete Mathematics Colloquium. See the poster and the webpage.
