The Lie structure on the Hochschild cohomology of a modular group algebra
Published 16 Mar 2011 in math.RA | (1103.3218v1)
Abstract: We prove that the Gerstenhaber bracket on the Hochschild cohomology of the group algebra of a cyclic group over a field of positive characteristic is not trivial. In this case, we relate the Lie algebra structure on the odd degrees of the Hochschild cohomology with a Witt-type algebra.
