Una particolare soluzione stazionaria della magnetofluidodinamica relativa ad una massa fluida cilindrica indefinita uniformemente rotante e soggetta alla propria gravitazione.
Sui sistemi dinamici soggetti a forze generalizzate riducibili a forma canonica
In this paper a dynamical system with n degrees of freedom is considered, under the action of forces depending not only on the coordinates and time, but also on the lagrangian velocities and the accelerations, for which there is the lagrangian function or a kinetic potential, so that the equations of motion are reducible to the canonical form. If the forces have a linear component in the lagrangian velocities, this component has a gyrostatic character. If the lagrangian function has terms of the...
