Simplicity of higher rank triplet W-algebras

Representation Theory 2022-06-24 v3

Abstract

We show that the higher rank triplet W-algebra is simple when p is bigger than or equal to h-1. Furthermore, we show that the Feigin-Tipunin's module over the higher rank triplet W-algebra introduced in arXiv:1002.5047 is simple if the parameter is in the closure of the fundamental alcove, and give the decomposition as a direct sum of simple modules over the affine W-algebras at level p-h.
