D.5.2.6 JuReTopDim

Procedure from library numerDecom.lib (see numerDecom_lib).

Return:
t=1 if w on a d-dimensional component of V(I), otherwise t=0.

Example:
 
LIB "numerDecom.lib";
ring r=(complex,16,I),(x,y,z),dp;
poly f1=(x2+y2+z2-6)*(x-y)*(x-1);
poly f2=(x2+y2+z2-6)*(x-z)*(y-2);
poly f3=(x2+y2+z2-6)*(x-y)*(x-z)*(z-3);
ideal J=f1,f2,f3;
list w=list(0.5372775295412116,-0.7105339291010922,-2.2817700129167831);
def D=JuReTopDim(J,w,2,2);
