Second Cohomology of q-deformed Witt superalgebras (1301.2704v1)
Published 12 Jan 2013 in math.RA and math.QA
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 $\sigma$-derivations instead of classical derivations.
