Hopf Bifurcation of Limit Cycles in Discontinuous Liénard SystemsDOI: 10.1155/2012/690453 Abstract: We consider a class of discontinuous Liénard systems and study the number of limit cycles bifurcated from the origin when parameters vary. We establish a method of studying cyclicity of the system at the origin. As an application, we discuss some discontinuous Liénard systems of special form and study the cyclicity near the origin.
