Tate Duality and Transfer for Symmetric Algebras Over Complete Discrete Valuation Rings

Representation Theory 2025-08-13 v1 Rings and Algebras

Abstract

We show that dualising transfer maps in Hochschild cohomology of symmetric algebras over complete discrete valuations rings commutes with Tate duality. This is analogous to a similar result for Tate cohomology of symmetric algebras over fields. We interpret both results in the broader context of Calabi-Yau triangulated categories.
