    • GERSTENHABER BRACKET ON HOPF ALGEBRA COHOMOLOGY 
      Karadag, Tekin (2021-05-26)
      M. A. Farinati, A. Solotar, and R. Taillefer showed that the Hopf algebra cohomology of a quasi-triangular Hopf algebra, as a graded Lie algebra under the Gerstenhaber bracket, is abelian. Motivated by the question of ...
    • On the Lie Algebra Structure on Hochschild Cohomology of Koszul Quiver Algebras 
      Oke, Tolulope Nathaneal (2021-07-23)
      We present the Gerstenhaber algebra structure on Hochschild cohomology of Koszul algebras defined by quivers and relations using the idea of homotopy liftings. There is a canonical way of constructing a minimal (graded) ...
