Shephard-Todd-Chevalley Theorem for skew polynomial rings
E. Kirkman, J. Kuzmanovich, J. J. Zhang
We prove the following generalization of the classical Shephard-Todd-Chevalley Theorem. Let be a finite group of graded algebra automorphisms of a skew polynomial ring $A:=k_{p…
Homological Transcendence Degree
Amnon Yekutieli, James J. Zhang
Let D be a division algebra over a base field k. The homological transcendence degree of D, denoted by Htr D, is defined to be the injective dimension of the enveloping algebra of…
Canonical Maps to Twisted Rings
D. Rogalski, J. J. Zhang
If A is a strongly noetherian graded algebra generated in degree one, then there is a canonically constructed graded ring homomorphism from A to a twisted homogeneous coordinate ri…
Multiplicities of Indecomposable Injectives
Amnon Yekutieli, James J. Zhang
Let A be a noncommutative noetherian with dualizing complex R. We study the multiplicities of indecomposable injectives in a minimal injective resolution of R. In particular when A…
Dualizing Complexes and Perverse Modules over Differential Algebras
Amnon Yekutieli, James J. Zhang
A differential algebra of finite type over a field k is a filtered algebra A, such that the associated graded algebra is finite over its center, and the center is a finitely genera…
