Normaliz :: normalToricRing(List, allComputations => ...)

normalToricRing(List, allComputations => ...) -- normalization of a toric ring

Synopsis

Description

The toric ring S is the monomial subalgebra of the basering generated by the monomials in the list L. The function computes the normalization T of S, which is the integral closure in its field of fractions. If the option allComputations is set to true, all data that has been computed by Normaliz is stored in a RationalCone in the CacheTable of the monomial subalgebra returned.

R=ZZ/37[x,y,t];
L={x^3, x^2*y, y^3, x*y^2};
