Abstract: Any analytic symplectic diffeomorphism $ \Phi $ of a symplectic manifold M is the Poincaré map of a real analytic Hamiltonian vector field $ {X_H}$. If $ \Phi $ does not have an analytic integral, then $ {X_H}$ has no analytic integral which is not a power series in H. Let $ M = {{\mathbf{R}}^2}$. If $ \Phi $ has a finite contact homoclinic point, then $ \Phi $ is nonintegrable. Also Moser's polynomial mapping is nonintegrable.
