The main results give conditions for the existence of infinitely many periodic orbits and heteroclinic cycles converging to singular orbits with respect to the Hausdorff distance.3323-3331engsingular perturbationstime-reversible systemsArtigo10.1090/S0002-9939-05-07894-9WOS:000231108100023Acesso aberto605095586116816166828677607174450000-0002-1430-59860000-0003-2037-8417
