Calculation of apsidal precession via perturbation theory
L. Barbieri, F. Talamucci
The calculus of apsidal precession frequencies of the planets is developed by means of a perturbation thecnique. A model of concentric rings (ring model), suitable for improving ca…

Synchronization of a double pendulum with moving pivots: a study of the spectrum
Federico Talamucci
The model we consider consists in a double pendulum set, where the pivot points are free to shift along a horizontal line. Moreover, the two pendula are coupled by means of a sprin…

An extended Lagrangian formalism
Federico Talamucci
A simple formal procedure makes the main properties of the lagrangian binomial extendable to functions depending to any kind of order of the time--derivatives of the lagrangian coo…
