Abstract

In this paper we describe several characterizations of basic finite-dimensional kk-algebras AA 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 \preccurlyeq, F(Δ)\mathcal{F} (_{\preccurlyeq} \Delta), the category of AA-modules with Δ_{\preccurlyeq} \Delta-filtrations, is closed under cokernels of monomorphisms, and classify quasi-hereditary algebras satisfying this property.
