Detecting finite flat dimension of modules via iterates of the Frobenius endomorphism

Douglas J. Dailey, Srikanth B. Iyengar, Thomas Marley

It is proved that a module $M$ over a Noetherian ring $R$ of positive characteristic $p$ has finite flat dimension if there exists an integer $t \geq 0$ such that $\operatorname{Tor}…

A change of rings result for Matlis reflexivity

Douglas Dailey, Thomas Marley

Let $R$ be a commutative Noetherian ring and $E$ the minimal injective cogenerator of the category of $R$ -modules. An $R$ -module $M$ is (Matlis) reflexive if the natural evaluation…
