A lecture note on covering theory in representation theory of algebras
Yuming Liu, Nengqun Li, Bohan Xing +1
Covering theory is an important tool in representation theory of algebras, however, the results and the proofs are scattered in the literature. We give an introduction to covering…
Fractional Brauer configuration algebras III: fractional Brauer graph algebras of type MS
Nengqun Li, Yuming Liu
In previous two papers, we defined fractional Brauer configuration algebras and developed their covering theory. In this paper, we study the representation theory of fractional Bra…
Fractional Brauer configuration algebras II: covering theory
Nengqun Li, Yuming Liu
In this paper, we develop a covering theory for the fractional Brauer configurations and connect it with the coverings of the associated quivers with relations in the sense of Mart…
Fractional Brauer configuration algebras I: definitions and examples
Nengqun Li, Yuming Liu
In 2017, Green and Schroll introduced a generalization of Brauer graph algebras which they call Brauer configuration algebras. In the present paper, we further generalize Brauer co…
