W-algebras and Lax type operators

Daniele Valeri (University of Glasgow)

Wednesday 29th September 16:00-17:00 Maths 110

Abstract

In the talk we will introduce the notion of W-algebras. In the so-called "quantum finite" case, these are certain associative algebras obtained via Hamiltonian reduction. It will be shown how to canonically associate to these algebras an object called Lax operator which allow to relate them to certain type of Yangians.

(Organizers note: this will be a board talk, so we are trying to set up Echo360 for online audience members. Guidance to come about this. It is unclear how well this will work, so please attend in person if you are keen to see the talk.)
