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