Summary
In the present paper we study by numerical methods a Hamiltonian model describing a chain of weakly coupled rotators. The existence of local phenomena of ordered and chaotic motions is illustrated and is interpreted, within classical perturbation theory, in terms of resonances.
Riassunto
Si studia con metodi numerici un modello hamiltoniano che descrive una catena di rotatori debolmente accoppiati. Si illustra in particolare come esistano fenomeni locali di moti ordinati e moti caotici e come questi si interpretino, nell’ambito della teoria classica delle perturbazioni, in termini di risonanze.
Резюме
В этой работе с помощью численных методов исследуется модель, описывающая цепочку слабо связанных ротаторов. Показывается и интерпретируется существование локальных явлений упорядоченного и хаотического движений в рамках классической теории возмущений, в термнах резонансов.
