Stratifications of finite directed categories and generalized APR tilting modules
Liping Li
A finite directed category is a -linear category with finitely many objects and an underlying poset structure, where is an algebraically closed field. This concept unifies s…
Representations of Modular Skew Group Algebras
Liping Li
In this paper we study representations of skew group algebras , where is a connected, basic, finite-dimensional algebra (or a locally finite graded algebra) over an algebra…
A generalized Koszul theory and its application in representation theory
Liping Li
There are many structures (algebras, categories, etc) with natural gradings such that the degree 0 components are not semisimple. Particular examples include tensor algebras with n…
A generalized Koszul theory and its relation to the classical theory
Liping Li
Let be a graded locally finite -algebra such that is an arbitrary finite-dimensional algebra satisfying a certain splitting condition.…
On the representation types of finite EI categories
Liping Li
A finite EI category is a small category with finitely many morphisms such that every endomorphism is an isomorphism. They include finite groups, finite posets and free categories…
A classification of algebras stratified for all preorders by Koszul theory
Liping Li
Let be a graded locally finite -algebra such that is an arbitrary finite-dimensional algebra satisfying some splitting condition. In th…
