Ladders of recollements of abelian categories
Nan Gao, Steffen Koenig, Chrysostomos Psaroudakis
Ladders of recollements of abelian categories are introduced, and used to address three general problems. Ladders of a certain height allow to construct recollements of triangulate…

Recollements of abelian categories and ideals in heredity chains - a recursive approach to quasi-hereditary algebras
Nan Gao, Steffen Koenig, Chrysostomos Psaroudakis
Recollements of abelian categories are used as a basis of a homological and recursive approach to quasi-hereditary algebras. This yields a homological proof of Dlab and Ringel's ch…

Ladders of recollements, categories of monomorphisms and singularity categories
Nan Gao, Chrysostomos Psaroudakis
In this paper we show that the (un)bounded derived categories(i) of the monomorphism category, (ii) of the morphism category and (iii) of the double morphism category, admi…
