Abstract

Let :=\glmn\ggg:=\gl_{m|n} be a general linear Lie superalgebra over an algebraically closed field \mathdsk=Fp\mathds{k}=\overline{\mathbb{F}}_p of characteristic p>2p>2. A module of \ggg is said to be of Kac-Weisfeiler if its dimension coincides with the dimensional lower bound in the super Kac-Weisfeiler property presented by Wang-Zhao in \cite{WZ}. In this paper, we verify the existence of the Kac-Weisfeiler modules for \glmn\gl_{m|n}. We also establish the corresponding consequence for the special linear Lie superalgebras slmn\mathfrak{sl}_{m|n} with restrictions p>2p>2 and p(mn)p\nmid(m-n).
