摘要
我们引入优势 Auslander-Gorenstein 代数类,作为高阶 Auslander 代数与极小 Auslander-Gorenstein 代数的推广,并给出其基本性质。我们还引入混合(预)簇倾斜模,作为(预)簇倾斜模的推广,并通过证明优势 Auslander-Gorenstein( respectively,Auslander-正则)代数双射对应于混合预簇( respectively,簇)倾斜模,建立 Auslander 型对应。我们证明 -表示有限代数 A 的任一平凡扩张代数 容许混合簇倾斜模,并表明这可视为众所周知的“-表示有限代数是分式 Calabi-Yau”结论的推广。我们证明 gendo-对称优势 Auslander-Gorenstein 代数的迭代 SGC-扩张容许混合预簇倾斜模。

Comments are welcome v2: minor changes to introduction, added and corrected references v3: We added a section about mixed cluster tilting modules in trivial extension algebras of d-representation-finite algebras and removed the section about Koszul duality. The results on Koszul duality will appear in forthcoming work
