Title: Limit Cycles In Discontinuous Classical Liénard Equations
Author: Miranda Martins R.
Mereu A.C.
Abstract: We study the number of limit cycles which can bifurcate from the periodic orbits of a linear center perturbed by nonlinear functions inside the class of all classical polynomial Liénard differential equations allowing discontinuities. In particular our results show that for any n>1 there are differential equations of the form x+f(x)x+x+sgn(x)g(x)=0, with f and g polynomials of degree n and 1 respectively, having [n/2]+1 limit cycles, where [.] denotes the integer part function. © 2014 Published by Elsevier Ltd.
