Comparing self-dual corings, Frobenius corings and Ringel self-duality
Tomasz Brzeziński, Teresa Conde, Steffen Koenig +1
Self-dual corings and self-dual algebra extensions are classified and these (self-)dualities are compared with Ringel (self-)duality, revealing fundamental differences. To each cor…

Nakayama-type phenomena in higher Auslander--Reiten theory
Gustavo Jasso, Julian Külshammer
This paper surveys recent contructions in higher Auslander--Reiten theory. We focus on those which, due to their combinatorial properties, can be regarded as higher dimensional ana…

From quasi-hereditary algebras with exact Borel subalgebras to directed bocses
Tomasz Brzeziński, Julian Külshammer, Steffen Koenig
Up to Morita equivalence, every quasi-hereditary algebra is the dual algebra of a directed bocs or coring. From the bocs, an exact Borel subalgebra is obtained. In this paper a cha…
