A necessary condition for the finiteness of A -good module categories

摘要

QUASI-HEREDITARY algebras were introduced by Cline et al. in order to study the highest weight categories in representation theory of semisimple Lie algebras and algebraic groups, Many important algebras such as hereditary algebras, Schur algebras andalgebras to blocks of the category 6 in ref., are typical examples of quasi-hereditary algebras.
