Classification of Brauer graph algebras under stable equivalence of Morita type
Nengqun Li, Pengyun Chen, Yuming Liu +1
The classification of Brauer graph algebras under derived equivalence was recently given by Opper and Zvonareva. In this paper, we prove that two Brauer graph algebras are derived…

Brauer graph algebras are closed under stable equivalence of Morita type
Pengyun Chen, Nengqun Li, Yuming Liu +1
We study stable equivalences of Brauer graph algebras. In particular, we prove that Brauer graph algebras are closed up to semisimple summands under stable equivalence of Morita ty…

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…
