Gelfand-Tsetlin modules for Lie algebras of rank $2$

Representation Theory 2025-01-10 v4

Abstract

We explicitly construct families of simple modules for Lie algebras of rank 22, on which certain commutative subalgebra acts diagonally and has a simple spectrum. In type AA these modules are well known generic Gelfand-Tsetlin modules and they can be viewed as such for other rank 22 Lie algebras.
