Let g be a basic classical Lie superalgebra. The aim of this article is the study of certain g-modules obtained by a method called homological induction. It is proved that the finite-dimensional typical modules can be obtained in this way and the Weyl-Kac character formula is deduced. It is also proved that the vector space spanned by the polynomial functions defined on a Cartan subalgebra h of g by H 7→ str(ρ(H)) , where m ∈ N and ρ is a finite-dimensional representation of g , contains all polynomials functions invariant under the Weyl group which are multiples of every isotropic root.
