Homological invariants of the arrow removal operation
Karin Erdmann, Chrysostomos Psaroudakis, Øyvind Solberg
In this paper we show that Gorensteinness, singularity categories and the finite generation condition Fg for the Hochschild cohomology are invariants under the arrow removal operat…
Torsion pairs and Ringel duality for Schur algebras
Karin Erdmann, Stacey Law
Let be a finite-dimensional algebra over a field of characteristic . We use a functorial approach involving torsion pairs to construct embeddings of endomorphism algebras…
Hybrid algebras
Karin Erdmann, Andrzej Skowroński
We introduce a new class of symmetric algebras, which we call hybrid algebras. This class contains on one extreme Brauer graph algebras, and on the other extreme general weighted s…
Some cluster tilting modules for weighted surface algebras
Karin Erdmann
Non-singular weighted surface algebras satisfy the necessary condition found in [6] for existence of cluster tilting modules. We show that any such algebra whose Gabriel quiver is…
