Simultaneous bifurcation of limit cycles for Piecewise Holomorphic systems

Armengol Gasull, Gabriel Rondón, Paulo R. da Silva

Let $\dot{z}=f(z)$ be a holomorphic differential equation with center at $p$. In this paper we are concerned about studying the piecewise perturbation systems $\dot{z}=f(z)+εR^\pm(…
