Abstract

We study the cohomology of Lie superalgebra of vector fields on affine super-spaces Am,n\mathbb{A}^{m,n} with trivial coefficients. In this paper we extend the methodology developed in the previous paper (arXiv:2210.16585) to perform the calculation for arbitrary dimensions (m,n)(m, n) with mnm \geq n. This combined with previously known results for other dimensions (m,n)(m, n) fully settles the local problem of Gelfand-Fuchs cohomology with trivial coefficients for super-manifolds. As part of the proof we also compute the cohomology of Lie superalgebras gl(m,n)\mathfrak{gl}(m,n) with coefficients given by Schur functors of the standard representation.
