Abstract

Let 𝒲 n be the Lie algebra of polynomial vector fields. We classify simple weight 𝒲 n -modules M with finite weight multiplicities. We prove that every such nontrivial module M is either a tensor module or the unique simple submodule in a tensor module associated with the de Rham complex on β„‚ n .
