[11] M. Peixoto, (Topology, t. 1, 1962, p. 101, Ann. of Math., t. 87, 1968, p. 422) has shown that if the dimension of the manifold is two, then the set of structurally stable vector field or dynamical system is a dense set on the set of all vector fields on this two dimensional manifold. In the case of differentiable maps i. e. C∞-maps, one can define stability as follows. Let Mn and Np be the two C∞-manifolds and let Cr (,) be the space of all maps from Mn to Np provided with the Cr-topology. A map is called stable if all'nearby maps' k are of the same type topologically as f and the diagram is commutative, i. e. fh = h'k where h and h' are ∈-homeomorphisms of Mn and Np.
