D.4.19.8 radicalMon
Procedure from library monomialideal.lib (see monomialideal_lib).
- Usage:
- radicalMon(I); I ideal
- Return:
- an ideal, the radical ideal of the ideal I.
(returns -1 if I is not a monomial ideal)
- Assume:
- I is a monomial ideal of the basering.
- Note:
- the minimal monomial generating set is returned.
Example:
| LIB "monomialideal.lib";
ring R = 0,(w,x,y,z,t),lp;
ideal I = w^3*x*y,w*x*y*z*t,x^2*y^2*z^2,x^2*z^4*t^3,y^3*z;
radicalMon(I);
==> _[1]=yz
==> _[2]=xzt
==> _[3]=wxy
