Response solutions in degenerate, quasi-periodically forced nonlinear oscillators
Resumen
EFor a quasi-periodically forced differential equation, response solutions are quasi- periodic ones whose frequency vector coincides with that of the forcing function and they are known to play a fundamental role in the harmonic and synchronizing behaviors of quasi- periodically forced oscillators. These solutions arewell-understood in quasi-periodically perturbed nonlinear oscillators either in the presence of large damping or in thenon- degenerate cases with small or free damping. This talk will present some recent results on the existence of responsive solutions in degenerate, quasi-periodically forced nonlinear oscillators with small or free damping.
