Weyl modules and Weyl functors for Lie superalgebras
Abstract
Given an algebraically closed field of characteristic zero, a Lie superalgebra over and an associative, commutative -algebra with unit, a Lie superalgebra of the form is known as a map superalgebra. Map superalgebras generalize important classes of Lie superalgebras, such as, loop superalgebras (where ), and current superalgebras (where ). In this paper, we define Weyl functors, global and local Weyl modules for all map superalgebras where is either with , or a finite-dimensional simple Lie superalgebra not of type . Under certain conditions on the triangular decomposition of these Lie superalgebras we prove that global and local Weyl modules satisfy certain universal and tensor product decomposition properties. We also give necessary and sufficient conditions for local (resp. global) Weyl modules to be finite dimensional (resp. finitely generated).
