$F$-pure threshold for the symmetric determinantal ring

Commutative Algebra 2025-08-26 v5

Abstract

We give a value for the FF-pure threshold at the maximal homogeneous ideal m\mathfrak{m} of the symmetric determinantal ring over a field of prime characteristic. The answer is characteristic independent, so we immediately get the log canonical threshold in characteristic zero as well.
