When is Frobenius epic?

Javier Carvajal-Rojas, Rankeya Datta, Noah Olander +1

We prove that a homomorphism of rings of prime characteristic is b-nil formally unramified if and only if its relative Frobenius is an epimorphism. We specialize this result under…

On the behavior of $F$ -signatures, splitting primes, and test modules under finite covers

Javier Carvajal-Rojas, Axel Stäbler

We give a comprehensive treatment on how $F$ -signatures, splitting primes, splitting ratios, and test modules behave under finite covers. To this end, we expand on the notion of tr…

The Uniform Symbolic Topology Property for Diagonally $F$ -regular Algebras

Javier Carvajal-Rojas, Daniel Smolkin

Let $k$ be a field of positive characteristic. Building on the work of the second named author, we define a new class of $k$ -algebras, called diagonally $F$ -regular algebras, for w…
