Abstract:

The presentation is based on a recent joint paper with Gianluca Gorni which revisits Noether's theorem on  constants of motion for Lagrangian mechanical systems in the ODE case.

In order to be as elementary as possible, the seminar deals with syncronous perturbed motions only.

Applications are shown to the Lane-Emden equation of Astrophysics and to mechanical systems with homogeneous potentials by means of nonlocal constants of motion obtained by our version of Noether's variational theorem.
