Effect of All Quadratic Terms on Third Order Oscillation

Z. Afsharnejad, O. Rabiei Motlagh, M. Tavakoli

Published Online: 03 Jun 2013DOI: 10.1080/1726037X.2008.10698543

In this paper: In this paper, we consider non-linear perturbation for the third order linear oscillator. Using the center manifold reduction, we reduced system into second order differential equation. Then we study...

Continuation of Periodic Orbits of a Third Order Oscillator under Autonomous Perturbation

Z. Afsharnejad, A. Golmakani

Published Online: 01 Nov 2006DOI: 10.1080/1726037X.2006.10698518

In this paper: We consider systems of nonlinear third-order differential equations depending on a small parameter such that the unperturbed system has a three dimension manifold of periodic solutions. We impose some...
