Summary
A class of integrable Euler equations of many interacting rigid bodies is constructed. Their integrability is proved by transforming then-Lax equation into the Duborvin equation which has a solution in terms of the Riemann θ-function. Some reductions of these equations are discussed.
Riassunto
Si costruisce una classe di equazioni di Eulero integrabili ai molti corpi rigidi che interagiscono. La loro integrabilità è provata trasformando la loro equazione di Lax nell’equazione di Dubrovin ehe ha una soluzione in termini della funzione θ di Riemann. Si discutono alcune riduzioni di queste equazioni.
