First Integrals vs Limit Cycles

Andrés G. García

Published 2019-09-17Version 1

This paper applies a recent result determining periodic orbits on the basis of first integrals, for Li\'enard systems. By solving a first order ODE with singularities, a crucial result is proved to locate intervals of single and isolated maximum amplitudes periodic orbits (limit cycles). With this result an upper bound for the number of limit cycles is provided. Some examples are presented along with conclusions and future work
