Cohomology of algebras over Hopf algebras
Cohomology of algebras over Hopf algebras
We present a cohomology theory for algebras which are modules over a given Hopf algebra.The algebras are commutative, the Hopf algebra cocommutative and under the module action the underlying coalgebra of the Hopf algebra " respects " the multiplication and unit in the algebras.The cohomology is defined by means of …
