چکیده
We calculate the Gerstenhaber bracket on Hopf algebra and Hochschild cohomologies of Taft Tp for any integer p>2 which is a nonquasi-triangular algebra. show that indeed zero cohomology Tp, as in all known quasi-triangular algebras. This example first computation Also, we find general formula with bijective antipode bar resolution reminiscent Gerstenhaber's original cohomology.

Gerstenhaber Bracket on Double Hochschild Complex and Deformation Theory
We construct a differential and a Lie bracket on the space {Hom(A, A)},k,l≥0 for any associative algebra A. The restriction of this bracket to the space {Hom(A, A)},k≥0 is exactly the Gerstenhaber bracket. We discuss some formality conjecture related with this construction. We also discuss some applications to deformation theory. 0. There exists a well-known way (due to Jim Stasheff) to define ...
متن کاملOrbifold Cup Products and Ring Structures on Hochschild Cohomologies
In this paper we study the Hochschild cohomology ring of convolution algebras associated to orbifolds, as well as their deformation quantizations. In the first case the ring structure is given in terms of a wedge product on twisted polyvectorfields on the inertia orbifold. After deformation quantization, the ring structure defines a product on the cohomology of the inertia orbifold. We study th...
متن کاملGerstenhaber Brackets on Hochschild Cohomology of Twisted Tensor Products
We construct the Gerstenhaber bracket on Hochschild cohomology of a twisted tensor product of algebras, and, as examples, compute Gerstenhaber brackets for some quantum complete intersections arising in work of Buchweitz, Green, Madsen, and Solberg. We prove that a subalgebra of the Hochschild cohomology ring of a twisted tensor product, on which the twisting is trivial, is isomorphic, as a Ger...
متن کاملCohomological Dimensions of Universal Cosovereign Hopf Algebras
We compute the Hochschild and Gerstenhaber-Schack cohomological dimensions of the universal cosovereign Hopf algebras, when the matrix of parameters is a generic asymmetry. Our main tools are considerations on the cohomologies of free product of Hopf algebras, and on the invariance of the cohomological dimensions under graded twisting by a finite abelian group.
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.
