CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe consider the Lagrangian $\frac{1}{2}(\dot{x}^2-\omega^2 x^2) + \frac{1}{2}\dot{q}^2 + (1+\delta(x))V(q)$ , $V$ $2 \pi$-periodic and $\delta$ bounded. The corresponding Euler–Lagrange equations have as the origin a saddle-centre stationary point whose (globally defined) centre manifold is foliated in periodic orbits. We prove that for $\omega$ small enough there exist multi-bump solutions, of large energy and heteroclinic to periodic orbits in the centre manifold.

| Abstract: | We consider the Lagrangian $\frac{1}{2}(\dot{x}^2-\omega^2 x^2) + \frac{1}{2}\dot{q}^2 + (1+\delta(x))V(q)$ , $V$ $2 \pi$-periodic and $\delta$ bounded. The corresponding Euler–Lagrange equations have as the origin a saddle-centre stationary point whose (globally defined) centre manifold is foliated in periodic orbits. We prove that for $\omega$ small enough there exist multi-bump solutions, of large energy and heteroclinic to periodic orbits in the centre manifold. |
