D.6.14.5 discr
Procedure from library spcurve.lib (see spcurve_lib).
- Usage:
- discr(sem,n); sem ideal, n integer
- Assume:
- sem is the versal deformation of an ideal of codimension 2.
The first n variables of the ring are treated as variables
all the others as parameters.
- Return:
- ideal describing the discriminant
- Note:
- This is not a powerful algorithm!
