Abstract:
We show that for every convex Lagrangian quadratic at infinity there is a real number $a_0$ such that for every $a>a_0$ the Lagrangian has a periodic orbit with action $a$. We attain estimates on the period and energy of the periodic orbits obtained. We also show that such a Lagrangian has periodic orbits of every period.References
