Derived Kunz and Radu--André Theorems

Commutative Algebra 2026-07-09 v1

Abstract

We extend Kunz's theorem and its relative form, the Radu--Andr\'e theorem, to animated algebras. The main inputs are the classical theorems, together with Bhatt and Scholze's vanishing of the Frobenius on negative cohomology.
