ABSTRACT
We consider a Hamiltonian equation of the form (HS) $$\ddot{q}(t) = -V_q(t, q(t))$$ for which V has two distinct non-degenerate maxima at different levels: 0 is a local maximum and $$\xi \neq 0$$ is an absolute maximum. Under standard non-degeneracy conditions on V, our main result is that there is a solution of (HS) homoclinic to 0. Then, supposing that another geometric condition holds, we show the existence of infinitely many solutions of (HS) homoclinic to 0 that are distinguished from one another by the number of times and regions where the solutions stay away from 0. As a corollary, we show that if there is a solution of (HS) homoclinic to $$\xi$$ , then there are infinitely many solutions of (HS) homoclinic to 0, distinguished by the number and position of intersections with 1/2.

    The aim of this Letter is to show that the singularities of integrable Hamil-tonian systems, besides being important for such systems themselves, also have many applications in the study of near-integrable systems. In particular, we will show how they are related to Kolmogorov' nondegeneracy...
