Bertotti, ML (Plenum Press, 1991)We outline a variational approach, developed to find periodic orbits of the satellite in the elliptic restricted problem with any value of the masses of the primaries. This approach leads to a multiplicity of generalized ...
Alessio, F; Bertotti, ML; Montecchiari, P (Springer Verlag (Germany), 1999)We study via variational methods some chaotic features of a class of almost periodic Lagrangian systems on a torus. In particular we show that slowly oscillating perturbations of such systems admit a multibump dynamics ...
