GLOBAL PHASE PORTRAITS OF QUADRATIC POLYNOMIAL DIFFERENTIAL SYSTEMS WITH A SEMI-ELEMENTAL TRIPLE NODE [PDF]
International Journal of Bifurcation and Chaos, 2013 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, 1902], are still open for this family.

Using Convolutional Neural Network to Emulate Seasonal Tropical Cyclone Activity
Journal of Advances in Modeling Earth Systems, 2023 It has been widely recognized that tropical cyclone (TC) genesis requires favorable large‐scale environmental conditions. Based on these linkages, numerous efforts have been made to establish an empirical relationship between seasonal TC activities and ...

Global dynamics of a non-symmetric cubic Lienard system
四川大学学报. 自然科学版, 2022 In this paper, we study global dynamics of a cubic non-symmetric Lienard system with global parameters, i.e., parameters are not required to be sufficiently small.

Global Phase Portraits of Quadratic Systems with a Complex Ellipse as Invariant Algebraic Curve [PDF]
Acta Mathematica Sinica, English Series, 2017 In this paper we study a new class of quadratic systems and classify all its phase portraits. More precisely, we characterize the class of all quadratic polynomial differential systems in the plane having a complex ellipse x^2 y^2 1=0 as invariant algebraic curve.

The phase portrait of the Hamiltonian system associated to a Pinchuk map
Anais da Academia Brasileira de CiênciasIn this paper we describe the global phase portrait of the Hamiltonian system associated to a Pinchuk map in the Poincaré disc. In particular, we prove that this phase portrait has 15 separatrices, five of them singular points, and 7 canonical regions ...

Nonlinear dynamic response and global stability of an air compressor vibration system
Journal of Low Frequency Noise, Vibration and Active Control, 2019 This study proposes a strategy for the vibration isolation mounting of an air compressor to attenuate the vibration near the primary resonance region by using a system with dynamic negative stiffness.

Global Phase Portrait of a Rolling Motion of Ships Equation
Qualitative Theory of Dynamical SystemsAbstract This paper studies the global dynamics of the rolling motion of ships in random beam seas model described by the equation $$\begin{aligned} \ddot{x}+ (2\mu + \delta x^2){\dot{x}} + \omega ^2 x-\frac{1}{a^2} x^3=0, \end{aligned}$$
