Weyl modules for Lie superalgebras

Abstract

We define global and local Weyl modules for Lie superalgebras of the form gA\mathfrak{g} \otimes A, where AA is an associative commutative unital C\mathbb{C}-algebra and g\mathfrak{g} is a basic Lie superalgebra or sl(n,n)\mathfrak{sl}(n,n), n2n \ge 2. Under some mild assumptions, we prove universality, finite-dimensionality, and tensor product decomposition properties for these modules. These properties are analogues of those of Weyl modules in the non-super setting. We also point out some features that are new in the super case.
