Nakayama automorphisms of graded Ore extensions of Koszul Artin-Schelter regular algebras
Y. Shen, Y. Guo
Let be a Koszul Artin-Schelter regular algebra, a graded automorphism of and a degree-one -derivation of . We introduce an invariant for called the -di…
The structure of connected (graded) Hopf algebras
G. -S. Zhou, Y. Shen, D. -M. Lu
In this paper, we establish a structure theorem for connected graded Hopf algebras over a field of characteristic by claiming the existence of a family of homogeneous generator…
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…
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…
