Global‐phase portrait and large‐degree asymptotics for the Kissing polynomials [PDF]

Studies in Applied Mathematics, 2020
We study a family of monic orthogonal polynomials that are orthogonal with respect to the varying, complex‐valued weight function, exp(nsz) , over the interval [−1,1] , where s∈C is arbitrary.

Review Article: "The Lagrangian description of aperiodic flows: a case study of the Kuroshio Current" [PDF]

Nonlinear Processes in Geophysics, 2012
This article reviews several recently developed Lagrangian tools and shows how their combined use succeeds in obtaining a detailed description of purely advective transport events in general aperiodic flows.

Global phase portraits of a predator–prey system

Electronic Journal of Qualitative Theory of Differential Equations, 2022
We classify the global dynamics of a family of Kolmogorov systems depending on three parameters which has ecological meaning as it modelizes a predator–prey system.

The phase portrait of the Hamiltonian system associated to a Pinchuk map

Anais da Academia Brasileira de Ciências, 2018
In 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 ...

Global Phase Portrait and Bifurcation Diagram for a Multi-Parametric Linear System

Journal of Southwest Jiaotong University, 2020
The goal of this article is to conduct a global dynamics study of a linear multiparameter system (real parameters (a,b,c) in R^3); for this, we take the different changes that these parameters present.

Local and global phase portrait of equation $\dot z=f(z)$

Discrete & Continuous Dynamical Systems - A, 2006
This paper studies the differential equation $\dot z=f(z)$, where $f$ is an analytic function in $\mathbb C$ except, possibly, at isolated singularities. We give a unify treatment of well known results and provide new insight into the local normal forms and global properties of the solutions for this family of differential equations.
