A freeness criterion for complexes with derived actions

Commutative Algebra 2025-02-28 v1 Number Theory

Abstract

Inspired by the patching method of Calegari and Geraghty, and a conjecture of de Smit that has been proved by the first author, we present a conjectural freeness criterion without patching for complexes over commutative noetherian local rings with derived actions, and verify it in several cases.
