Hello everyone,

Today Max Forester will be speaking in seminar (2:30 in room 405).

His title and abstract are here:

Title: Genus bounds in right-angled Artin groups

Abstract: I will discuss how to find lower bounds for stable commutator length in rightangled Artin groups. The method has two parts: an easy topological argument, and an argument involving properties of CAT(0) cube complexes.
