Closed access Metadata (CSL-JSON)
DOI 10.2140/jsag.2019.9.89
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

We describe a Macaulay2 package for computations in prime characteristic commutative algebra.This includes those for Frobenius powers and roots, p -e -linear and p e -linear maps, singularities defined in terms of these maps, different types of test ideals and modules, and ideals compatible with a given p -e -linear map.
