Gerstenhaber-Schack Cohomology for Hom-bialgebras and Deformations (1608.02084v1)
Published 6 Aug 2016 in math.QA and math.RA
Abstract: Hom-bialgebras and Hom-Hopf algebras are generalizations of bialgebra and Hopf algebra structures, where associativity and coassociativity conditions are twisted by a homomorphism. The purpose of this paper is to define a Gerstenhaber-Schack cohomology complex for Hom-bialgebras and then study one parameter formal deformations.
