Abstract

Let Am,nA_{m,n} be the tensor product of the Laurient polynomial algebra in mm even variables and the exterior algebra in nn odd variables over the complex field \bC\bC, and the Witt superalgebra Wm,nW_{m,n} be the Lie superalgebra of superderivations of Am,nA_{m,n}. In this paper, we classify the simple weight Wm,nW_{m,n} modules with finite-dimensional weight spaces with respect to the standard Cartan algebra of Wm,0W_{m,0}. Every such module is either a simple quotient of a tensor module or a module of highest weight type.
