D.4.13.12 isartinianMon

Procedure from library monomialideal.lib (see monomialideal_lib).

Usage:
isartinianMon(I); I ideal.

Return:
1, if ideal is artinian; 0, otherwise.
(return -1 if ideal I is not a monmomial ideal).

Assume:
I is a monomial ideal of the basering.

Example:
 
LIB "monomialideal.lib";
ring R = 0,(w,x,y,z,t),lp;
ideal I = w^4,x^3,y^4,z^2,t^6,w^2*x^2*y,w*z*t^4,x^2*y^3,z^2*t^5;
isartinianMon (I);
==> 1
ideal J = w^4,x^3,y^4,z^2,w^2*x^2*y,w*z*t^4,x^2*y^3,z^2*t^5;
isartinianMon (J);
==> 0
