Derived Kunz and Radu--André Theorems
Daniel Fink
We extend Kunz's theorem and its relative form, the Radu--André theorem, to animated algebras. The main inputs are the classical theorems, together with Bhatt and Scholze's vanish…

-smooth factorization for Noetherian -finite rings
Manuel Blickle, Daniel Fink
We show that any homomorphism between Noetherian -finite rings can be factored into a regular morphism between Noetherian -finite rings followed by a surjection. This result…

On the injective dimension of unit Cartier and Frobenius modules
Manuel Blickle, Daniel Fink, Alexandria Wheeler +1
Let be a regular -finite ring of prime characteristic . We prove that the injective dimension of every unit Frobenius module in the category of unit Frobenius modules…
