Upper bounds on Arnold diffusion times via Mather theory / U. Bessi, L. Chierchia, E. Valdinoci. - In: JOURNAL DE MATHÉMATIQUES PURES ET APPLIQUÉES. - ISSN 0021-7824. - 80:1(2001), pp. 105-129.
Abstract:
We consider several Hamiltonian systems for which the existence of Arnold's mechanism for diffusion (whiskered tori, transition ladder, etc.) has been proven. By means of Mather theory we show that the diffusion time may be bounded by a power of the homoclinic splitting.
