Weyl modules for toroidal Lie algebras

Representation Theory 2022-03-04 v1

Abstract

In this paper we study Weyl modules for a toroidal Lie algebra \CT\CT with arbitrary nn variables. Using the work of Rao \cite{1995}, we prove that the level one global Weyl modules of \CT\CT are isomorphic to suitable submodules of a Fock space representation of \CT\CT upto a twist. As an application, we compute the graded character of the level one local Weyl module of \CT\CT, thereby generalising the work of Kodera \cite{ko}.
