Normaliz :: normalToricRing(List)

normalToricRing(List) -- 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.
