摘要：

In this paper, we study Poincar & eacute;, Hopf and homoclinic bifurcations of limit cycles for planar nearHamiltonian systems. Our main results establish Hopf and homoclinic bifurcation theories by higher order Melnikov functions, obtaining conditions on upper bounds and lower bounds of the maximum number of limit cycles. As an application, we concern a cubic near -Hamiltonian system, and study Hopf and homoclinic bifurcations in detail, finding more limit cycles than [26]. (c) 2024 Elsevier Inc. All rights reserved.
