TWELVE LIMIT CYCLES IN A CUBIC HAMILTONIAN SYSTEM OF PLANAR WITH FIVE-ORDER PERTURBED TERM
摘要
Abstract
Through both qualitative analysis and numerical exploration the author demonstrates that there are twelve limit cycles in the cubic Hamiltonian system of planar with perturbed term of degree 5, and the distributed orderliness of the 12 limit cycles are presented.关键词
