Flat morphisms with regular fibers do not preserve $F$ -rationality

Eamon Quinlan-Gallego, Austyn Simpson, Anurag K. Singh

For each positive prime integer $p$ we construct a standard graded $F$ -rational ring $R$ , over a field $K$ of characteristic $p$ , such that $R \otimes_{K} K$ is not $F$ -rati…

A formalism of $F$ -modules for rings with complete local finite $F$ -representation type

Eamon Quinlan-Gallego

We develop a formalism of unit $F$ -modules in the style of Lyubeznik and Emerton-Kisin for rings which have finite $F$ -representation type after localization and completion at ever…
