| dc.description.abstract | In this work, we prove a Nekhoroshev theorem for the Toda chain with Dirichlet boundary conditions, i.e., fixed ends. The Toda chain is a special case of a Fermi-Pasta-Ulam (FPU) chain, and in view of the unexpected recurrence phenomena observed numerically in these chains, it has been conjectured that theory of perturbed integrable systems could be applied to these chains, especially since the Toda chain has been shown to be a completely integrable system. Whereas various results have already been obtained for the periodic lattice, the Dirichlet chain is more important from the point of view of applications, since the famous numerical experiments have been performed for this type of system. Mathematically, the Dirichlet chain can be treated by exploiting symmetries of the periodic chain. Precisely, by considering the phase space of the Dirichlet chain as an invariant submanifold of the periodic chain, namely the fixed point set of a certain symmetry of the periodic chain, the results obtained for the periodic chain can be used to obtain similar results for the Dirichlet chain. The Nekhoroshev theorem is a perturbation theory result which does not have the probabilistic character of other results such as those of the KAM theorem. | de_CH |
