- 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],
which is a graded subalgebra of R[t]. The degree-k-component is the integral
closure of the k-th power of I.
In contrast to the previous version, the library uses 'normal.lib' to compute the
integral closure of R[It]. This improves the performance considerably.
