theorem ISO:
for F being Field,
    p being non constant Element of the carrier of Polynom-Ring F
holds (Polynom-Ring F)/({p}-Ideal), Polynom-Ring(p) are_isomorphic
proof
let F be Field,
    p be non constant Element of the carrier of Polynom-Ring F;
set R = Polynom-Ring F, S = Polynom-Ring(p);
R/ker(poly_mod p), S are_isomorphic by RING_2:16;
hence thesis by kerp;
end;
