MultiplierIdeals is a package for computing multiplier ideals, log canonical thresholds, and jumping numbers, using specialized routines wherever possible.
The package Dmodules provides computations of multiplier ideals, log canonical thresholds, and jumping numbers of arbitrary ideals using general algorithms.
This package provides alternatives for special classes of ideals, including monomial ideals, hyperplane arrangements, generic determinantal ideals, and binomial ideals (currently, ideals of curves in 3-space parametrized by monomials). These special computations are typically much faster than general methods and can often handle larger examples.
Version 1.1 of this package was accepted for publication in volume 7 of the journal The Journal of Software for Algebra and Geometry on 5 June 2015, in the article Software for multiplier ideals. That version can be obtained from the journal or from the Macaulay2 source code repository, http://github.com/Macaulay2/M2/blob/master/M2/Macaulay2/packages/MultiplierIdeals.m2, commit number a71903e3507b0384ece1ed43f815b9344258ed1a.
This documentation describes version 1.1 of MultiplierIdeals.
