Melnikov deviations and limit cycles for Lienard equations
Palabras clave:
Vector, Function, Parameter (en)Descargas
In this paper we analyze the method of small parameter and we calculate explicitly the derivatives of order two and three with respect to the parameter in the case of a homoclinic orbit and in the case of periodic orbits. Also, we apply this method to the Lienard equation of degree five on the plane:
