Frobenius test exponents for parameter ideals in generalized Cohen-Macaulay local rings
Craig Huneke, Mordechai Katzman, Rodney Y. Sharp +1
This paper studies Frobenius powers of parameter ideals in a commutative Noetherian local ring of prime characteristic . For a given ideal $\fa$ of , there is a power …
On the Hartshorne--Speiser--Lyubeznik Theorem about Artinian modules with a Frobenius action
Rodney Y. Sharp
Let be a commutative Noetherian local ring of prime characteristic. The purpose of this paper is to provide a short proof of G. Lyubeznik's extension of a result of R. Hartshor…
Graded annihilators of modules over the Frobenius skew polynomial ring, and tight closure
Rodney Y. Sharp
This paper is concerned with the tight closure of an ideal in a commutative Noetherian local ring of prime characteristic . Several authors, including R. Fedder, K.-i. Watan…
A criterion for regularity of local rings
Tom Bridgeland, Srikanth Iyengar
It is proved that a noetherian commutative local ring A containing a field is regular if there is a complex M of free A-modules with the following properties: M_i=0 for i not in [0…
