Commonly Graded Algebras and Their Homological Properties
Haonan Li, Quanshui Wu
In this article, we study bounded-below locally finite -graded algebras, which are referred to as commonly graded algebras in literature. Commonly graded algebras have…

Noncommutative resolutions of AS-Gorenstein isolated singularites
Haonan Li, Menda Shen, Quanshui Wu
In this paper, we investigate noncommutative resolutions of (generalized) AS-Gorenstein isolated singularities. Noncommutative resolutions in graded case are achieved as the graded…

Regular -graded local rings and Graded Isolated Singularities
Haonan Li, Quanshui Wu
In this note we first study regular -graded local rings. We characterize commutative noetherian regular -graded local rings in similar ways as in the usual…
