Improving a method for the study of limit cycles of the Liénard equation
نویسنده
چکیده
In recent papers we have introduced a method for the study of limit cycles of the Liénard system : ẋ = y − F (x) , ẏ = −x , where F (x) is an odd polynomial. The method gives a sequence of polynomials Rn(x), whose roots are related to the number and location of the limit cycles, and a sequence of algebraic approximations to the bifurcation set of the system. In this paper, we present a variant of the method that gives very important qualitative and quantitative improvements. PACS numbers : 05.45.+b , 02.30.Hq , 02.60.Lj , 03.20.+i

On the number of limit cycles of the Liénard equation
In this paper, we study a Liénard system of the form ẋ = y−F (x) , ẏ = −x, where F (x) is an odd polynomial. We introduce a method that gives a sequence of algebraic approximations to the equation of each limit cycle of the system. This sequence seems to converge to the exact equation of each limit cycle. We obtain also a sequence of polynomials Rn(x) whose roots of odd multiplicity are related...

We consider the class of polynomial differential equation x&= , 2(,)(,)(,)nnmnmPxyPxyPxy++++2(,)(,)(,)nnmnmyQxyQxyQxy++&=++. For where and are homogeneous polynomials of degree i. Inside this class of polynomial differential equation we consider a subclass of Darboux integrable systems. Moreover, under additional conditions we proved such Darboux integrable systems can have at most 1 limit cycle.
متن کاملAlgebraic approximations to bifurcation curves of limit cycles for the Liénard equation
In this paper, we study the bifurcation of limit cycles in Liénard systems of the form dx dt = y − F (x) , dy dt = −x , where F (x) is an odd polynomial that contains, in general, several free parameters. By using a method introduced in a previous paper, we obtain a sequence of algebraic approximations to the bifurcation sets, in the parameter space. Each algebraic approximation represents an e...
متن کاملSmall amplitude limit cycles for the polynomial Liénard system
We prove a quadratic in m and n estimate for the maximal number of limit cycles bifurcating from a focus for the Liénard equation x+f(x) _ x+ g(x) = 0; where f and g are polynomials of degree m and n respectively. In the proof we use a bound for the number of double points of a rational a¢ ne curve.
متن کاملOn limit cycles of the Liénard equation with Z2 symmetry
This paper considers the limit cycles in the Liénard equation, described by €xþ f ðxÞ _ xþ gðxÞ 1⁄4 0, with Z2 symmetry (i.e., the vector filed is symmetric with the y-axis). Particular attention is given to the existence of small-amplitude (local) limit cycles around fine focus points when g(x) is a third-degree, odd polynomial function and f(x) is an even function. Such a system has three fix...
