Yangian characters and classical W-algebras

Abstract

The Yangian characters (or q-characters) are known to be closely related to the classical W-algebras and to the centers of the affine vertex algebras at the critical level. We make this relationship more explicit by producing families of generators of the W-algebras from the characters of the Kirillov–Reshetikhin modules associated with multiples of the… (More)
