Generalizations of the relationship between quasi-hereditary algebras and directed bocses

Abstract

Koenig, K\"ulshammer and Ovsienko showed that Morita equivalence classes of quasi-hereditary algebras are in one-to-one correspondence with equivalence classes of the module categories over directed bocses. In this article, we extend this result to $\Delta$-filtered algebras and $\overline{\Delta}$-filtered algebras.
