Skew Calabi-Yau property of normal extensions
G. -S. Zhou, Y. Shen, D. -M. Lu
We prove that the skew Calabi-Yau property is preserved under normal extension for locally finite positively graded algebras. We also obtain a homological identity which describes…
Ext-algebras of graded skew extensions
Y. Shen, X. Wang, G. -S. Zhou
In this paper, we study the Ext-algebras of graded skew extensions. For a connected graded algebra and a graded automorphism , we analyze the Yoneda product of the Ext-algeb…
Nakayama automorphisms of twisted tensor products
Y. Shen, G. -S. Zhou, D. -M. Lu
In this paper, we study homological properties of twisted tensor products of connected graded algebras. We focus on the Ext-algebras of twisted tensor products with a certain form…
Behavior of the Auslander condition with respect to regradings
G. -S. Zhou, Y. Shen, D. -M. Lu
We show that a noetherian ring graded by an abelian group of finite rank satisfies the Auslander condition if and only if it satisfies the graded Auslander condition. In addition,…
