Equivalence of the Melnikov Function Method and the Averaging Method

Qualitative Theory of Dynamical Systems, 2015
In this paper, the authors study the problem of equivalence between the Melnikov method and the averaging method for studying the number of limit cycles which can bifurcate from the period annulus of planar analytic differential systems.

Melnikov function and Poincaré map

Applied Mathematics and Mechanics, 1988
The following ODE is investigated: \(x''+g(x)=\epsilon \mu f(x,x')+\epsilon \delta h(x,x',\omega t)\) where \(h(x,x',\omega t)\) is periodic in t. A relationship between the Melnikov function and the Poincaré mapping is established and a new proof for the Melnikov method is given. Some illustrative examples are also presented.

Second order Melnikov function and its application

Physics Letters A, 1990
Abstract Based on Melnikov's method, the second order Melnikov function for the study of subharmonic and ultrasubharmonic orbits in a class of planar Hamiltonian systems is derived. Using this function the existence criterion of subharmonic and ultrasubharmonic orbits is set. A nonlinear oscillator subject to perturbation as example is discussed.

Some properties of Melnikov functions near a cuspidal loop

Science China Mathematics, 2023
Limit cycle bifurcations of a near-Hamiltonian system near a cuspidal loop is studied. A method using first-order Melnikov functions is employed. A general method to obtain the number of limit cycles near the cuspidal loop is presented. The results are exemplified on a Liénard-like system.
