Perturbed normalizers and Melnikov functions

Journal of Mathematical Analysis and Applications, 2018
Consider a \(C^{\infty}\) smooth family of real planar vector fields \(\left(X_\varepsilon\right)_\varepsilon\) of the form \[ X_\varepsilon (x) \, = \, X_0(x) + \varepsilon X_1(x) + \varepsilon^2 X_2(x) + \, \ldots \, + \varepsilon^n X_n(x) + \mathcal{O}\left(\varepsilon^{n+1}\right), \] for some integer \(n \geq 1\), \(x \in \mathbb{R}^2\) and ...

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.

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.
