摘要

Considering the general linear Lie superalgebra gl(m|n)=gl(m|n)_0¯¯⊕gl(m|n)_1¯¯ over C, we first formulate a super version of Vust theorem associated with a principal nilpotent element e∈gl(m|n)_0¯¯. As an application of this theorem, we then obtain a Schur-Sergeev duality for principal finite W-superalgebras which is partially a super version of Brundan-Kleshchev's higher level Schur-Weyl duality established in [7].
