Enclosing a periodic orbit of processes in the plane

Berenice Camargo Damasceno, Luciano Barbanti

Resumo


We give here a method for the definition of a closed continuous curve C in the y ≥ 0 semi-plane coming from an equation of the Liénard type, in such a way that C surrounds the y ≥ 0 - piece of a periodic orbit of the equation itself.


Palavras-chave


Liénard equations, periodic orbit, ODE, egress points.
