Quasi-Hereditary Orderings of Nakayama Algebras
Quasi-Hereditary Orderings of Nakayama Algebras
To determine an algebra is quasi-hereditary is a difficult problem. An effective method, Green-Schroll set, is introduced in this paper to tackle this problem. It is well known that an algebra is quasi-hereditary if and only if it admits a quasi-hereditary ordering of simple modules. Let $A$ be a Nakayama …
