COHOMOLOGY OF FROBENIUS ALGEBRAS AND THE YANG-BAXTER EQUATION
COHOMOLOGY OF FROBENIUS ALGEBRAS AND THE YANG-BAXTER EQUATION
A cohomology theory for multiplications and comultiplications of Frobenius algebras is developed in low dimensions, in analogy with Hochschild cohomology of bialgebras, based on deformation theory. Concrete computations are provided for key examples. Skein theoretic constructions give rise to solutions to the Yang-Baxter equation, using multiplications and comultiplications of Frobenius …
