BV-algebra Structures and Hochschild (Co)homology

Diego Duarte Vogel

Universidad de los Andes, Colombia   -

In this talk we will recall the BV-algebra structures of the Hochschild cohomology of symmetric algebras and its relation with string topology. We will present the calculations of these structures for the group ring of finitely generated abelian groups. If time permits, we will present the notion of Hochschild Tate cohomology defined by Buchweitz and the BV-algebra structure defined by Wang for self-injective algebras. As an example, we will show the calculations for the group ring of cyclic groups.

Joint work with Andrés Angel (Universidad de los Andes, Colombia).
