  报告摘要：Quasi-hereditary algebras introduced by Cline, Parshall and Scott are mainly devised to study those algebras arising from algebraic Lie theory. Prominent examples include Schur algebras, block algebras of BGG category O and their variations. In the study of such algebras, modules with \Delta-filtration are of central importance.In this talk, we consider for each such a module, instead of its usual radical and socle filtration, the so-called \Delta-radical and \Delta-socle filtration. We study the properties of these filtrations, and apply them to the study of Schur algebras. This is based on a joint work with Professor Jun Hu, still in progress.
