Euler number and Betti numbers of homology groups of pre Lie superalgebra

Abstract

First we recall homology groups of prer Lie superalgebras. Then introducing double weighted chain spaces, we deal with pre Lie superalgebra of multi-vector fields with polynomial coefficients on n-dimensional number space. The bracket is Schouten bracket. We have several results about Euler number and Betti numbers of those homology groups of special pre Lie superalgebra.
