Geometric Group Theory Without Boundaries
21 Jun 2021
Along with Macarena Arenas, Sami Douba and Abdul Zalloum, I am organizing a virtual “summer school” that began today and will run until July 2. More info is available on the summer school website. This is the second iteration of the summer school! I spoke in the first iteration; the purpose of this post is to house links to the notes, recordings and exercises for the mini-course I gave.
I gave three lectures in this summer school on Bass and Serre’s theory of graphs of groups and groups acting on trees.
Here are notes (with the annotations I added live) for the lectures, as well as links to recordings of the lectures.
