- Usage:
- isprimeMon (I); I ideal
- Return:
- 1, if I is prime; 0, otherwise.
(returns -1 if I is not a monomial ideal) - Assume:
- I is a monomial ideal of the basering.
LIB "monomialideal.lib"; ring R = 0,(w,x,y,z,t),lp; ideal I = w,y,t; isprimeMon (I); ==> 1 ideal J = w,y,t,x*z; isprimeMon (J); ==> 0 |
