Description
Lienard systems of the form $\ddot{x}+εf(x)\dot{x}+x=0$, with f(x) an even function, are studied in the strongly nonlinear regime ($ε\to\infty$). A method for obtaining the number, amplitude and loci of the limit cycles of these equations is derived. The accuracy of this method is checked in several examples. Lins-Melo-Pugh conjecture for the polynomial case is true in this regime.
