陈建功大讲堂——代数讲坛(2022-3)
摘要:It is well known that there is a nice connection between artin algebras of finite representation type and Auslander algebras. For Auslander algebras, the category of all projective modules is an abelian category and so there is a close relationship between the abelianness of this category and being of finite representation type. Now let $ n $ be a positive integer. To get a higher dimensional analog of this connection, we characterize $ n $-Auslander algebras by the abelianness of the category of all modules with projective dimension less than $ n $ and then by higher Auslander correspondence we obtain a new characterization of the class of artin algebras having $ n $-cluster tilting modules. We also present a Gorenstein analog of this result. This talk is based on a joint work with Mohammad Keshavarz.
