Cohomology of Frobenius Algebras and the Yang-Baxter Equation
J. Scott Carter, Alissa S. Crans, Mohamed Elhamdadi +2
A cohomology theory for multiplications and comultiplications of Frobenius algebras is developed in low dimensions in analogy with Hochschild cohomology of bialgebras based on defo…

Cohomology of the adjoint of Hopf algebras
J. Scott Carter, Alissa S. Crans, Mohamed Elhamdadi +1
A cohomology theory of the adjoint of Hopf algebras, via deformations, is presented by means of diagrammatic techniques. Explicit calculations are provided in the cases of group al…
