On finite dimensional representations of finite W-superalgebras
Abstract
Let be a basic Lie superalgebra, (resp.) be the finite W-(resp.super-) algebras constructed from a fixed nilpotent element in . Based on a relation between finite W-algebra and W-superalgebra found recently by the author and Shu, we study the finite dimensional representations of finite W-superalgebras in this paper. We first formulate and prove a version of Premet's conjecture for the finite W-superalgebras from basic simple Lie superalgebras. As in the W-algebra case, the Premet's conjecture is very close to give a classification to the finite dimensional simple -modules. In the case of is Lie superalgebras of basic type \Rmnum{1}, we prove the set of simple -supermodules is bijective with that of simple -modules; presenting a triangular decomposition to the tensor product of with a Clifford algebra, we also give an algorithm to compute the character of the finite dimensional simple -supermodules with integral central character.
