> | ### D.4.27 primdecint_lib Library: primdecint.lib Purpose: primary decomposition of an ideal in the polynomial ring over the integers Authors: G. Pfister pfister@mathematik.uni-kl.de A. Sadiq afshanatiq@gmail.com S. Steidel steidel@mathematik.uni-kl.de Overview: A library for computing the primary decomposition of an ideal in the polynomial ring over the integers, Z[x_1,...,x_n]. The first procedure 'primdecZ' can be used in parallel. The coefficients must always be ZZ. Reference: Pfister, Sadiq, Steidel , "An Algorithm for primary decomposition in polynomial rings over the integers" , arXiv:1008.2074 Procedures:
