Abstract

Let Am,nA_{m,n} be the tensor product of the polynomial algebra in mm even variables and the exterior algebra in nn odd variables over the complex field \C\C, 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 non-trivial simple bounded weight Wm,nW_{m,n} modules with respect to the standard Cartan algebra of Wm,nW_{m,n}. Any such module is a simple quotient of a tensor module F(P,L(V1V2))F(P,L(V_1\otimes V_2)) for a simple weight module PP over the Weyl superalgebra Km,n\mathcal K_{m,n}, a finite-dimensional simple \glm\gl_m-module V1V_1 and a simple bounded \gln\gl_n-module V2V_2.
