摘要
In this paper we describe several characterizations of basic finite-dimensional -algebras A stratified for all linear orders, and classify their graded algebras as tensor algebras satisfying some extra property. We also discuss whether for a given linear order , , the category of A-modules with -filtrations, is closed under cokernels of monomorphisms, and classify quasi-hereditary algebras satisfying this property.
