D.8.1.1 ffsolve

Procedure from library ffsolve.lib (see ffsolve_lib).

Usage:
ffsolve(I[, L]); I ideal, L list of strings

Return:
list L, the common roots of I as ideal

Assume:
basering is a finite field of type (p^n,a)

Example:
 
LIB "ffsolve.lib";
ring R = (2,a),x(1..3),lp;
minpoly=a2+a+1;
ideal I;
I[1]=x(1)^2*x(2)+(a)*x(1)*x(2)^2+(a+1);
I[2]=x(1)^2*x(2)*x(3)^2+(a)*x(1);
I[3]=(a+1)*x(1)*x(3)+(a+1)*x(1);
ffsolve(I);
==> [1]:
==>    _[1]=x(3)+1
==>    _[2]=x(2)+(a+1)
==>    _[3]=x(1)+(a+1)
==> [2]:
==>    _[1]=x(3)+1
==>    _[2]=x(2)+(a)
==>    _[3]=x(1)+1
