Melnikov analysis in nonsmooth differential systems with nonlinear switching manifold
(2019-09-05)
We study the family of piecewise linear differential systems in the plane with two pieces separated by a cubic curve. Our main result is that 7 is a lower bound for the Hilbert number of this family. In order to get our ...

Coherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
(2000-08-01)
The atomic tunneling between two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well time-dependent trap was studied. For the slowly varying trap, synchronization of oscillations of the trap with oscillations ...

Limit cycles in planar piecewise linear differential systems with nonregular separation line
(2016-12-15)
In this paper we deal with planar piecewise linear differential systems defined in two zones. We consider the case when the two linear zones are angular sectors of angles α and 2π−α, respectively, for α∈(0,π). We study the ...
Análise da dinâmica de um sistema vibrante não ideal de dois graus de liberdade
(Universidade Estadual Paulista (Unesp), 2005-07-25)
Neste trabalho apresentamos um estudo da dinâmica de um sistema vibrante não ideal, composto por um motor e uma mola, conhecido como vibrador centrífugo. O objetivo deste estudo é mostrar a diferença de comportamento do ...
