D.14.7.7 boolean_ideal

Procedure from library polybori.lib (see polybori_lib).

Usage:
boolean_ideal(Is[, rb]); Is Ideal, rb boolean ring

Return:
default: ideal Is in the representation of the boolean ring rb==boolean_poly_ring(basering); optional input: rb boolean ring

Example:
 
LIB "polybori.lib";
ring r0=2,x(1..4),lp;
poly f1=x(1)^2+2*x(2)*(x(3))-x(4)^3;
poly f2=x(1)^2-x(3)*x(1);
poly f3=x(2)+5-2*x(1);
poly f4=x(1)*x(2)-x(3);
ideal I=f1,f2,f3,f4;
boolean_ideal(I);
ring r1=0,x,Dp;
poly f1=x3+2*x+1;
poly f2=x10-x5+2x;
poly f3=19;
ideal I=f1,f2,f3;
boolean_ideal(I);
ring r2=32003,(x,y,z),Dp;
bring bbr2=r2;
poly f1=xyz+20*x^2*y-3*xz+15;
poly f2=32002*xy+z2;
poly f3=19;
ideal I=f1,f2,f3;
boolean_ideal(I);
boolean_ideal(I,bbr2);
