Perturbed damped pendulum: finding periodic solutions
Douglas Duarte Novaes
Using the damped pendulum system we introduce the averaging method to study the periodic solutions of a dynamical system with small perturbation. We provide sufficient conditions f…

On the periodic solutions of a perturbed double pendulum
Jaume Llibre, Douglas Duarte Novaes, Marco Antonio Teixeira
We provide sufficient conditions for the existence of periodic solutions of the planar perturbed double pendulum with small oscillations.
