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…
