The Frobenius functor and injective modules

Commutative Algebra 2012-03-01 v2

Abstract

We investigate commutative Noetherian rings of prime characteristic such that the Frobenius functor applied to any injective module is again injective. We characterize the class of one-dimensional local rings with this property and show that it includes all one-dimensional F-pure rings.
