Let Λ be an Artin algebra. In this paper, the notion of -Gorenstein cluster tilting subcategories will be introduced. It is shown that every -cluster tilting subcategory of mod-Λ is -Gorenstein if and only if Λ is an Iwanaga-Gorenstein algebra. Moreover, it will be shown that an -Gorenstein cluster tilting subcategory of mod-Λ is an -cluster tilting subcategory of the exact category , the subcategory of all Gorenstein projective objects of mod-Λ. Some basic properties of -Gorenstein cluster tilting subcategories will be studied. In particular, we show that they are n-resolving, a higher version of resolving subcategories.

-Gorenstein丛集倾斜子类别
令Λ为Artin代数。在本文中,...的概念-将介绍Gorenstein群集倾斜子类别。结果表明,每-Λ的-集群倾斜子类别为 当且仅当Λ是Iwanaga-Gorenstein代数时,才使用-Gorenstein。而且,将显示出-mod-Λ的-Gorenstein簇倾斜子类别是 -确切类别的集群倾斜子类别 ,是mod-Λ的所有Gorenstein射影对象的子类别。的一些基本特性-将研究Gorenstein群集倾斜子类别。特别是,我们表明它们是n-解析的,是解析子类别的更高版本。
