Zero-Hopf bifurcation in the general Van der Pol-Duffing equation
Murilo Cândido, Claudia Valls
We study analytically the coexistence of multiple periodic solutions and invariant tori in the general Van der Pol-Duffing oscillator equations. We use several results related to t…

Periodic solutions and invariant torus in the Rössler System
Murilo R. Cândido, Douglas D. Novaes, Claudia Valls
The Rössler System is characterized by a three-parameter family of quadratic 3D vector fields. There exist two one-parameter families of Rössler Systems exhibiting a zero-Hopf equi…
