Definition. Une fonction f : E ? F est injective si tout élément y de F a au plus un antécédent (et éventuellement aucun). Les fonctions f représentées ci-
This definition of injectivity is also often phrased in the contrapositive form: a function f : X ? Y is injective if x1 = x2 ? f(x1) = f(x2).

Thus the definition of divisible means in some rough sense that any element of the module may be divided by an arbitrary nonzero element of the ring. Lemma 2.
