Weyl modules for queer Lie superalgebras

Representation Theory 2023-03-01 v1

Abstract

We define global and local Weyl modules for qAq \otimes A, where qq is the queer Lie superalgebra and AA is an associative commutative unital C\mathbb{C}-algebra. We prove that global Weyl modules are universal highest weight objects in certain category upto parity reversing functor Π\Pi. Then with the assumption that AA is finitely generated and with a special technical condition which simple root system of qq satisfy it is shown that the local Weyl modules are finite dimensional. Further they are universal highest map-weight objects in certain category upto Π\Pi. Finally we prove a tensor product property for local Weyl modules.
