Resumo
In this work a discontinuous planar piecewise differential system was considered. In particular, the conditions for the existence of limit cycles in a system with 2 foci and 2 linear fields was studied. We obtain a computational method to construct cycles in such systems and theoretical approaches to verify if the obtained cycles are limit cycles.
