The organizers of the Algebraic Graph Theory International Webinar would like to invite you to join us and other colleagues on November 9, 2021, at 7pm Central European Summer Time (= 6pm UTC), for the next presentation delivered by Gabriel Verret. 

The title of Martin's talk: Local actions and eigenspaces of vertex-transitive graphs

Abstract:
When studying families of vertex-transitive graphs, it is often important to have control on the size of vertex-stabilisers of the automorphism groups. It turns out that the "local" action of the automorphism group plays a crucial role. I'll explain this connection, describe some known results and another more recent connection with the size of the eigenspaces of such graphs over finite fields.
