$F$-thresholds of filtrations of ideals

Commutative Algebra 2023-12-14 v1

Abstract

In this article, we extend the notion of the FF-thresholds of ideals to the FF-thresholds for filtrations of ideals. The existence of FF-thresholds of filtrations are established for various types of filtrations. Moreover, various necessary and sufficient conditions for finiteness of FF-thresholds are given. We also give some effective upper bounds of the symbolic FF-thresholds. A sufficient condition for symbolic FF-splitting in terms of its symbolic FF-threshold is given. We compute the symbolic FF-thresholds of various determinantal ideals, FF-K\"onig ideals, and many more.
