Symbolic power containments in singular rings in positive characteristic
Eloísa Grifo, Linquan Ma, Karl Schwede
The containment problem for symbolic and ordinary powers of ideals asks for what values of and we have . Over a regular ring, a result by Ein-Lazarsf…
An analog of adjoint ideals and PLT singularities in mixed characteristic
Linquan Ma, Karl Schwede, Kevin Tucker +2
We use the framework of perfectoid big Cohen-Macaulay algebras to define a class of singularities for pairs in mixed characteristic, which we call purely BCM-regular singularities,…
RationalMaps, a package for Macaulay2
C. J. Bott, S. Hamid Hassanzadeh, Karl Schwede +1
This paper describes the RationalMaps package for Macaulay2. This package provides functionality for computing several aspects of rational maps such as whether a map is birational,…
Covers of rational double points in mixed characteristic
Javier Carvajal-Rojas, Linquan Ma, Thomas Polstra +2
We further the classification of rational surface singularities. Suppose is a strictly Henselian regular local ring of mixed characteristic $(0, p…
The FrobeniusThresholds package for Macaulay2
Daniel J. Hernández, Karl Schwede, Pedro Teixeira +1
This article describes the \emph{Macaulay2} package \emph{FrobeniusThresholds}, designed to estimate and calculate -pure thresholds, more general -thresholds, and related num…
