Summary
We give numerical evidence for the existence of chaotic motions and of a transition to stochasticity in the classical problem of a heavy rigid body with a fixed point, by studying a perturbation of the Euler-Poinsot case. This gives also numerical evidence for the non-integrability of this problem.
Riassunto
In questo lavoro si mostra numericamente l’esistenza di moti caotici e di una transizione alla stocasticità nel problema classico del corpo rigido pesante con un punto fisso, studiando una perturbazione del caso di Eulero-Poinsot. In tal modo si dà anche una dimostrazione numerica della non integrabilità di questo problema.
Резюме
Мы приводим численное подтверждение существования хаотических движений и перехода к стохастичности в классической проблеме тяжелого жесткого тела с фиксированной точкой, исследуя возмущение для случая Эйлера-Пуансо. Также приводится численное подтверждение для неинтегрируемости такой проблемы.

It might, however, be interesting to note that in the well-known Lorentz system of equations, which is nonconservative, but presents some formal analogies with the Euler equations (withA=2,B=C=1), the existence of a very complex structure of chaotic motions has been numerically observed.
