Guodong Zhou (Lausanne), Comparison morphisms and Hochschild cohomology.

Abstract:
We give a recursive method to construct comparison morphisms between two projective resolutions of a module. Then we apply this method to the computation of the Lie bracket of the Hochschild cohomology of some classes of algebras, including group algebras, monomial algebras and Koszul algebras.
