A note on a piecewise-linear Duffing-type system
G Tigan, A Astolfi - International Journal of Bifurcation and Chaos, 2007 - World Scientific
In [Tonnelier, 2005] it was suggested that the number of limit cycles in a piecewise-linear
system could be closely related to the number of zones, that is, the number of parts of the …

Thirteen limit cycles for a class of Hamiltonian systems under seven-order perturbed terms
G Tigan - Chaos, Solitons & Fractals, 2007 - Elsevier
In this paper we study the existence, number and distribution of limit cycles of the perturbed
Hamiltonian system: where μ+ β= n, 0< a< b< 1, 0< ε≪ 1, u, v, λ are the real parameters and …
