Cactus groups and monodromy
April 22, 2022 from 15:30 to 16:30 (Montreal/EST time)
Colloquium presented by Joel Kamnitzer (University of Toronto)
The cactus group is a cousin of the braid group and shares many of its beautiful properties. It is the fundamental group of the moduli space of points on RP^1. It also acts on many collections of combinatorial objects. I will explain how we use the cactus group to understand monodromy of eigenvectors for Gaudin algebras.
