Algebra seminar by Daniel Woodhouse

On Wednesday the 26th of February 2020, Daniel Woodhouse (University of Oxford) will be visiting the Charlotte Scott Centre for Algebra and giving a talk at 3pm in INB3305. The details of his talk are as follows:
Title: Leighton’s graph covering theorem
Abstract: Leighton’s theorem for graphs states that any pair of finite graphs with common universal covers have a common finite cover.

Equivalently, this says that any pair of uniform lattices in the automorphism groups of a tree can be commensurated.

I will discuss the significance of this theorem, recent generalizations, and how it can be applied in geometric group theory.
