D.4.22 reesclos_lib

Library:
reesclos.lib
Purpose:
procedures to compute the int. closure of an ideal
Author:
Tobias Hirsch, email: hirsch@math.tu-cottbus.de

Overview:
A library to compute the integral closure of an ideal I in a polynomial ring R=k[x(1),...,x(n)] using the Rees Algebra R[It] of I. It computes the integral closure of R[It] (in the same manner as done in the library 'normal.lib'), which is a graded subalgebra of R[t]. The degree-k-component is the integral closure of the k-th power of I.

Procedures:

D.4.22.1 ReesAlgebra  computes the Rees Algebra of an ideal I
D.4.22.2 normalI  computes the integral closure of an ideal I using R[It]
