The converse is not true in general, because if F = R and B is positive deﬁnite, then B(v,v) = 0 implies v = 0 so the quadric deﬁned by B is the empty set. A little later we shall work over the complex numbers in general, as it makes life easier. But for the moment, to get some intuition, let us consider conics in P2(R)
