1
作者 Yun Tian, Yepeng Xing (Dept. of Math., Shanghai Normal University, Shanghai 200234) 《Annals of Differential Equations》 2010年第2期222-226,共5页
In this paper, we investigate the limit cycle bifurcations in a cubic near-Hamiltonian system by perturbing a cuspidal loop and prove that 5 limit cycles can appear in a neighborhood of the cuspidal loop.
