A quintic polynomial differential system with eleven limit cycles at the infinity
In this article, a recursion formula for computing the singular point quantities of the infinity in a class of quintic polynomial systems is given. The first eleven singular point quantities are computed with the computer algebra system Mathematica. The conditions for the infinity to be a center are derived as well. Finally, a system that allows the appearance of eleven limit cycles in a small ...
متن کاملLimit Cycles for a Generalized Kukles Polynomial Differential Systems
We study the limit cycles of a generalized Kukles polynomial differential systems using the averaging theory of first and second order.
متن کاملLIMIT CYCLES FOR m–PIECEWISE DISCONTINUOUS POLYNOMIAL LIÉNARD DIFFERENTIAL EQUATIONS
We provide lower bounds for the maximum number of limit cycles for the m–piecewise discontinuous polynomial differential equations ẋ = y + sgn(gm(x, y))F (x), ẏ = −x, where the zero set of the function sgn(gm(x, y)) with m = 2, 4, 6, . . . is the product of m/2 straight lines passing through the origin of coordinates dividing the plane in sectors of angle 2π/m, and sgn(z) denotes the sign funct...
متن کاملLimit Cycles of the Generalized Polynomial Liénard Differential Equations
We apply the averaging theory of first, second and third order to the class of generalized polynomial Liénard differential equations. Our main result shows that for any n, m ≥ 1 there are differential equations of the form ẍ+f(x)ẋ+g(x) = 0, with f and g polynomials of degree n and m respectively, having at least [(n + m− 1)/2] limit cycles, where [·] denotes the integer part function.
متن کاملThe number of limit cycles of a quintic polynomial system
In this paper we consider the bifurcation of limit cycles of the system ˙ x = y(x 2 − a 2)(y 2 − b 2) + εP(x, y), ˙ y = −x(x 2 − a 2)(y 2 − b 2) + εQ (x, y) for ε sufficiently small, where a, b ∈ R − {0}, and P, Q are polynomials of degree n, we obtain that up to first order in ε the upper bounds for the number of limit cycles that bifurcate from the period annulus of the quintic center given b...
