Zoom seminar Quadratic forms, Linear algebraic groups and Beyond, 8:30am

I will talk about a recent paper with Ben Martin and Gerhard Roehrle on subgroups containing regular unipotent elements in reductive algebraic groups. The main result which I will describe is not itself new (it is due to Testerman and Zalesski), but the new proof we came up with is worth sharing, since it is very short, free from the case-checking of the original, and only rests on quite well-known basic properties of algebraic groups. I will also describe some generalisations and extensions.
