In these invariant sets, using the Darboux theory of integrability, we prove the non-existence of periodic solutions and we study their dynamics. Moreover, we find three invariant sets of dimension four where the flow is integrable.7187-7192engArtigo10.1088/1751-8113/40/26/006WOS:000247189800015Acesso restrito66828677607174450000-0003-2037-8417
