Fine Hochschild invariants of derived categories for symmetric algebras

Alexander Zimmermann

Let $A$ be a symmetric $k$ -algebra over a perfect field $k$ . Külshammer defined for any integer $n$ a mapping $ζ_n$ on the degree 0 Hochschild cohomology and a mapping $κ_n$ on t…

Generalized Reynolds ideals for non-symmetric algebras

Christine Bessenrodt, Thorsten Holm, Alexander Zimmermann

We show how to extend the theory of generalized Reynolds ideals, as introduced by B. K"ulshammer, from symmetric algebras to arbitrary finite-dimensional algebras (in positive char…
