Macaulay2 Packages

QuillenSuslin.m2 - (Joint with Branden Stone, last updated September 2013)
A package containing methods for computing free bases for projective modules over polynomial rings and solving related problems concerning completion of unimodular rows to square invertible matrices in Macaulay2. This package implements the algorithms given by Logar-Sturmfels in their 1992 paper ``Algorithms for the Quillen-Suslin Theorem'' with some modifications as described in a Ph.D. thesis ``Algorithmic Analysis of Presentations of Groups and Modules'' by Anna Fabianska. Algorithms for computing completions of unimodular rows over Laurent polynomial rings, due to Park, are also provided. Some explanation of the general algorithm is given in this paper.
