Note on the cohomology of color Hopf and Lie algebras
Let A be a (G,χ)-Hopf algebra with bijective antipode and let M be a G-graded A-bimodule. We prove that there exists an isomorphism HH∗gr(A,M)∼= Ext∗A-gr ( K,ad (M) ) , where K is viewed as the trivial graded A-module via the counit of A, adM is the adjoint A-module associated to the graded A-bimodule M and HH∗gr denotes the G-graded Hochschild cohomology. As an application, we deduce that the ...
متن کاملGorenstein global dimensions for Hopf algebra actions
Let $H$ be a Hopf algebra and $A$ an $H$-bimodule algebra. In this paper, we investigate Gorenstein global dimensions for Hopf algebras and twisted smash product algebras $Astar H$. Results from the literature are generalized.
متن کاملA Note on Divided Powers in a Hopf Algebra
The algebraic structure of a Hopf algebra over a field was established by A. Borel [l] (see Théorème 6.1). The theorem asserts that if a Hopf algebra is finitely generated in each dimension and the field is perfect then it is algebraically isomorphic to a tensor product of monogenic exterior and polynomial algebras (the latter possibly truncated if the characteristic is prime). Under more restr...

متن کاملOn Cohomology of Hopf Algebroids
Inspired by [3] we introduce the concept of extended Hopf algebra and consider their cyclic cohomology in the spirit of Connes-Moscovici [3, 4, 5]. Extended Hopf algebras are closely related, but different from, Hopf algebroids. Their definition is motivated by attempting to define cyclic cohomology of Hopf algebroids in general. Many of Hopf algebra like structures, including the Connes-Moscov...
