BCM-thresholds of hypersurfaces

Commutative Algebra 2024-04-12 v1

Abstract

In this paper, we use big Cohen-Macaulay algebras to define a characteristic free analog of the FF-thresholds, which we call BCM-thresholds, in the case of principal ideals. We prove that, similarly to the case of the FF-thresholds, the set of BCM-thresholds and the set of BCM-jumping numbers agree. We also relate some BCM-thresholds to splittings of maps from the ring to a big Cohen-Macaulay algebra.
