CINECA IRIS Institutional Research Information System
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.
EnglishCombining an old idea of Olver and Rosenau with the classifica- tion of second and third order homogeneous Hamiltonian operators we classify compatible trios of two-component homogeneous Hamiltonian operators. The trios yield pairs of compatible bi-Hamiltonian opera- tors whose structure is a direct generalization of the bi-Hamiltonian pair of the KdV equation. The bi-Hamiltonian pairs give rise to multi- parametric families of bi-Hamiltonian systems. We recover known ex- amples and we find apparently new integrable systems whose central invariants are non-zero; this shows that new examples are not Miura- trivial.

| Abstract: | Combining an old idea of Olver and Rosenau with the classifica- tion of second and third order homogeneous Hamiltonian operators we classify compatible trios of two-component homogeneous Hamiltonian operators. The trios yield pairs of compatible bi-Hamiltonian opera- tors whose structure is a direct generalization of the bi-Hamiltonian pair of the KdV equation. The bi-Hamiltonian pairs give rise to multi- parametric families of bi-Hamiltonian systems. We recover known ex- amples and we find apparently new integrable systems whose central invariants are non-zero; this shows that new examples are not Miura- trivial. |
