Cactus groups and monodromy

Colloque par Joel Kamnitzer (Université McGill)

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.
