In this article, we study the expansion of the first Melnikov function of a near-Hamiltonian system near a heteroclinic loop with a cusp and a saddle or two cusps, obtaining formulas to compute the first coefficients of the expansion. Then we use the results to study the problem of limit cycle bifur

โฆ Synopsis
In this paper we study the bifurcations of a pair of nonorientable heteroclinic cycles. In addition to the obvious and important bifurcation ''โ-explosion,'' several other bifurcations, for example, homoclinic and heteroclinic bifurcation behaviors, are described in terms of symbolic sequences and symbolic descriptions of trajectories staying forever in a sufficiently small neighborhood of the cycles are established.

flow on X = need not consist only of equilibria. Indeed, when dim 2<dim 1 the dynamics on the perturbed orbit X = will generally be more complicated than just consisting of equilibria. Lauterbach and Roberts [15] show that, depending on the pair 1 and 2, article no.
This paper shows that asymmetrically perturbed, symmetric Hamiltonian systems of the form with analytic \* j (=)=O(=), have at most two limit cycles that bifurcate for small ={0 from any period annulus of the unperturbed system. This fact agrees with previous results of Petrov, Dangelmayr and Gucke
Time finite element analysis (TFEA) is used to determine the accuracy, stability, and limit cycle behavior of the milling process. Predictions are compared to traditional Euler simulation and experiments. The TFEA method forms an approximate solution by dividing the time in the cut into a finite num
