چکیده
We provide the 22 different global phase portraits in the Poincaré disk of all centers of the so called Kukles polynomial differential systems of the form ẋ = −y, ẏ = x + Q5(x, y), where Q5 is a real homogeneous polynomial of degree 5 defined in R.

Centers and limit cycles of polynomial differential systems of degree 4 via averaging theory
In this paper we classify the phase portraits in the Poincaré disc of the centers of the generalized class of Kukles systems ẋ = −y, ẏ = x+ axy + bxy, symmetric with respect to the y-axis, and we study, using the averaging theory up to sixth order, the limit cycles which bifurcate from the periodic solutions of these centers when we perturb them inside the class of all polynomial differential s...

In this paper we classify the global phase portraits in the Poincaré disc of all quartic polynomial differential systems with a uniform isochronous center at the origin.
متن کاملGlobal Phase Portraits of Quadratic Systems with an Ellipse and a Straight Line as Invariant Algebraic Curves
In this paper we study a new class of integrable quadratic systems and classify all its phase portraits. More precisely, we characterize the class of all quadratic polynomial differential systems in the plane having an ellipse and a straight line as invariant algebraic curves. We show that this class is integrable and we provide all the different topological phase portraits that this class exhi...
متن کاملCenter of Planar Quintic Quasi–homogeneous Polynomial Differential Systems
In this paper we first characterize all quasi–homogeneous but non–homogeneous planar polynomial differential systems of degree five, and then among which we classify all the ones having a center at the origin. Finally we present the topological phase portrait of the systems having a center at the origin.
متن کاملGlobal phase Portraits of quadratic Polynomial differential Systems with a Semi-Elemental Triple Node
Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical problems, and in particular, Hilbert’s 16th problem [Hilbert, 1900, Hilbert, 1902], are still open for this family. In this article we make a global study of the familyQTN ...
