Finding nilpotents with Wolmer Vasconcelos
-
Craig Huneke
Abstract
This paper discusses the nilradical of ideals, especially concerning ideas surrounding the algorithm to compute the nilradical of ideals in polynomial rings which appears in the paper “Direct Methods for Primary Decomposition,” by David Eisenbud, Wolmer Vasconcelos, and the current author. One new algorithm is also presented.
