Chaotic dynamics in an impact problem
Stefano Marò
We consider the model describing the vertical motion of a ball falling with constant acceleration on a wall and elastically reflected. The wall is supposed to move in the vertical…
A mechanical counterexample to KAM theory with low regularity
Stefano Marò
We give a mechanical example concerning the fact that some regularity is necessary in KAM theory. We consider the model given by the vertical bouncing motion of a ball on a periodi…
Coexistence of bounded and unbounded motions in a bouncing ball model
Stefano Marò
We consider the model describing the vertical motion of a ball falling with constant acceleration on a wall and elastically reflected. The wall is supposed to move in the vertical…
Diffusion and chaos in a bouncing ball model
Stefano Marò
We consider the vertical motion of a free falling ball bouncing elastically on a racket moving in the vertical direction according to a regular periodic function . We give a suf…
Twist dynamics and Aubry-Mather sets around a periodically perturbed point-vortex
Stefano Marò, Vìctor Ortega
We consider the model of a point-vortex under a periodic perturbation and give sufficient conditions for the existence of generalized quasi-periodic solutions with rotation number.…
