McKay Matrices for Finite-dimensional Hopf Algebras
Georgia Benkart, Rekha Biswal, Ellen Kirkman +2
For a finite-dimensional Hopf algebra , the McKay matrix of an -module encodes the relations for tensoring the simple -modules with . We prove results about t…
The Gerstenhaber structure on the Hochschild cohomology of a class of special biserial algebras
Joanna Meinel, Van C. Nguyen, Bregje Pauwels +2
We determine the Gerstenhaber structure on the Hochschild cohomology ring of a class of self-injective special biserial algebras. Each of these algebras is presented as a quotient…
Finite generation of some cohomology rings via twisted tensor product and Anick resolutions
Van C. Nguyen, Xingting Wang, Sarah Witherspoon
Over a field of prime characteristic , we prove that the cohomology rings of some pointed Hopf algebras of dimension are finitely generated. These are Hopf algebras aris…
The Tate-Hochschild cohomology ring of a group algebra
Van C. Nguyen
We show that the Tate-Hochschild cohomology ring of a finite group algebra is isomorphic to a direct sum of the Tate cohomology rings of the centralizers of conj…
