Tensor Product Realizations of Simple Torsion Free Modules
Published online by Cambridge University Press: 20 November 2018
Abstract
Let $\mathcal{G}$ be a finite dimensional simple Lie algebra over the complex numbers $C$. Fernando reduced the classification of infinite dimensional simple $\mathcal{G}$-modules with a finite dimensional weight space to determining the simple torsion free $\mathcal{G}$-modules for $\mathcal{G}$ of type $A$ or $C$. These modules were determined by Mathieu and using his work we provide a more elementary construction realizing each one as a submodule of an easily constructed tensor product module.
