From Brauer graph algebras to biserial weighted surface algebras. (arXiv:1706.07693v1 [math.RT])

来源于:arXiv
We prove that the class of Brauer graph algebras coincides with the class of indecomposable idempotent algebras of biserial weighted surface algebras. These algebras are associated to triangulated surfaces with arbitrarily oriented triangles. Hence biserial weighted surface algebras can be considered as desingularizations of Brauer graph algebras. 查看全文>>
