The Limit Cycles of Lienard Equations in the Strongly Non-Linear Regime

Jose-Luis Lopez, Ricardo Lopez-Ruiz

Lienard systems of the form $\ddot{x}+\epsilon f(x)\dot{x}+x=0$, with f(x) an even function, are studied in the strongly nonlinear regime ($\epsilon \to \infty$). A method for obtaining the number,…
