normalToricRing(MonomialSubalgebra) -- normalization of a toric ring
Synopsis
Usage:
normalToricRing S
Function:
normalToricRing
Inputs:
an object of class
MonomialSubalgebra
, the toric ring
Optional inputs
:
allComputations => ...
,
grading => ...
,
Outputs:
an object of class
MonomialSubalgebra
, the normalization of the toric ring
Description
The toric ring S is the monomial subalgebra given. The function computes the normalization T of S, which is the integral closure in its field of fractions.
R=ZZ/37[x,y,t];
