Ring theoretical properties of affine cellular algebras
Paula A. A. B. Carvalho, Steffen Koenig, Christian Lomp +1
As a generalisation of Graham and Lehrer's cellular algebras, affine cellular algebras have been introduced in [12] in order to treat affine versions of diagram algebras like affin…
Derived equivalences, restriction to self-injective subalgebras and invariance of homological dimensions
Ming Fang, Wei Hu, Steffen Koenig
Derived equivalences between finite dimensional algebras do, in general, not pass to centraliser (or other) subalgebras, nor do they preserve homological invariants of the algebras…
Recollements and stratifying ideals
Lidia Angeleri H\" ugel, Steffen Koenig, Qunhua Liu +1
Surjective homological epimorphisms with stratifying kernel can be used to construct recollements of derived module categories. These `stratifying' recollements are derived from re…
