Periodic second-order systems and coupled forced Van der Pol oscillators
Feliz Minhós, Sara Perestrelo
We present an existence and localization result for periodic solutions of second-order non-linear coupled planar systems, without requiring periodicity for the non-linearities. The…

Heteroclinic and homoclinic solutions for nonlinear second-order coupled systems with phi-Laplacians
Robert de Sousa, Feliz Minhós
In this paper we present sufficient conditions for the existence of heteroclinic or homoclinic solutions for second order coupled systems of differential equations on the real line…
