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.
EnglishThe purpose of this paper is the derivation of multivalue numerical methods for Hamiltonian problems. It is known from the literature that such methods cannot be symplectic; however, they can satisfy an alternative property, known as G-symplecticity, which still allows a long time conservation of the Hamiltonian of the dynamical system under investigation. New G-symplectic methods are derived and compared with existing ones on a selection of Hamiltonian systems.
