Perfectoid multiplier/test ideals in regular rings and bounds on symbolic powers
Using perfectoid algebras we introduce a mixed characteristic analog of the multiplier ideal,
respectively test ideal, from characteristic zero, respectively p> 0 p> 0, in the case of a …

Quantifying singularities with differential operators
H Brenner, J Jeffries, L Núñez-Betancourt - Advances in Mathematics, 2019 - Elsevier
The F-signature of a local ring of prime characteristic is a numerical invariant that detects
many interesting properties. For example, this invariant detects (non) singularity and strong …

Symbolic powers of edge ideals of graphs
Y Gu, HT Hà, JL O'Rourke… - Communications in …, 2020 - Taylor & Francis
Let G be a graph and let I= I (G) be its edge ideal. When G is unicyclic, we give a
decomposition of symbolic powers of I in terms of its ordinary powers. This allows us to …

The v-number of edge ideals
D Jaramillo, RH Villarreal - Journal of Combinatorial Theory, Series A, 2021 - Elsevier
The aim of this work is to study the v-number of edge ideals of clutters. We relate the v-
number with the regularity of edge ideals and classify W 2 graphs. If the edge ideal of a …

The Structure of Symbolic Powers of Matroids
P Mantero, V Nguyen - arXiv preprint arXiv:2406.13759, 2024 - arxiv.org
We describe the structure of the symbolic powers $ I^{(\ell)} $ of the Stanley-Reisner ideals,
and cover ideals, $ I $, of matroids. We (a) prove a structure theorem describing a minimal …
