- Overview:
- A library for determining if the toric ideal of an affine monomial curve is a complete intersection with NO
NEED of computing explicitly a system of generators of such ideal. It also contains procedures to obtain the
minimum positive multiple of an integer which is in a semigroup of positive integers.
The procedures are based on a paper by Isabel Bermejo, Ignacio Garcia and Juan Jose Salazar-Gonzalez: 'An
algorithm to check whether the toric ideal of an affine monomial curve is a complete intersection', Preprint.
Procedures:
D.13.1.1 BelongSemig | | checks whether n is in the semigroup generated by v; |
D.13.1.2 MinMult | | computes k, the minimum positive integer such that k*a is in the semigroup of positive integers generated by the elements in b. |
D.13.1.3 CompInt | | checks wether I(d) is a complete intersection or not. |
