Tate-Hochschild Cohomology of Radical Square Zero Algebras
Published 26 Nov 2015 in math.RT, math.KT, and math.RA | (1511.08348v2)
Abstract: For algebras with radical square zero, we give a combinatorial description to the Tate-Hochschild cohomology. We compute the Gerstenhaber algebra structure on the Tate-Hochschild cohomology for some classes of such algebras.
