Sharp estimates for the number of limit cycles in discontinuous generalized Liénard equations

Tiago M. P. de Abreu, Ricardo Miranda Martins

In this paper, we study the maximum number of limit cycles for the piecewise smooth system of differential equations $\dot{x}=y, \ \dot{y}=-x-\varepsilon \cdot (f(x)\cdot y +{\rm s…
