The number of medium amplitude limit cycles of some generalized Liénard systems

چکیده
We will consider two special families of polynomial perturbations of the linear center. For the resulting perturbed systems, which are generalized Liénard systems, we provide the exact upper bound for the number of limit cycles that bifurcate from the periodic orbits of the linear center.

Limit cycles in generalized Liénard systems
This paper presents some new results which we obtained recently for the study of limit cycles of nonlinear dynamical systems. Particular attention is given to small limit cycles of generalized Liénard systems in the vicinity of the origin. New results for a number of cases of the Liénard systems are presented with the Hilbert number, b H ði; jÞ 1⁄4 b H ðj; iÞ, for j = 4, i = 10,11,12,13; j = 5,...
متن کاملNonexistence of Limit Cycles for Planar Systems of Liénard-type
A new method for the nonexistence of limit cycles of the planar system including a generalized Liénard-type system is introduced. It is given by constructing a curve with some invariance defined on a half-open interval and has useful powers for the case which the equilibrium point is stable specially. Moreover, it is also applied to systems with several equilibrium points. It shall be shown tha...
متن کاملGeneralized Liénard Equations, Cyclicity and Hopf–Takens Bifurcations
We investigate the bifurcation of small–amplitude limit cycles in generalized Liénard equations. We use the simplicity of the Liénard family, to illustrate the advantages of the approach based on Bautin ideals. Essentially, this Bautin ideal is generated by the so–called Lyapunov quantities, that are computed for generalized Liénard equations and used to detect the presence of a Hopf– Takens bi...
متن کاملOn the Number of Limit Cycles for Discontinuous Generalized Liénard Polynomial Differential Systems
In this paper, we investigate the number of limit cycles for a class of discontinuous planar differential systems with multiple sectors separated by many rays originating from the origin. In each sector, it is a smooth generalized Liénard polynomial differential system x′ = −y + g1(x) + f1(x)y and y′ = x + g2(x) + f2(x)y, where fi(x) and gi(x) for i = 1, 2 are polynomials of variable x with any...
متن کاملLimit Cycles of a Class of Generalized Liénard Polynomial Equations
In this paper we study the maximum number of limit cycles of the following generalized Liénard polynomial differential system of the first order ẋ = y2p−1 ẏ = −x2q−1 − εf (x, y) where p and q are positive integers, ε is a small parameter and f (x, y) is a polynomial of degree m. We prove that this maximum number depends on p, q and m. AMS subject classification:
