Second Cohomology of q-deformed Witt superalgebras

preprint2013arXivOpen access

Abstract

The purpose of this paper is to compute the second adjoint cohomology group of q-deformed Witt superalgebras. They are Hom-Lie superalgebras obtained by q-deformation of Witt Lie superalgebra, that is one considers σσ-derivations instead of classical derivations.
