Global phase portraits of a predator–prey system

open access: yesElectronic 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.

Exact traveling-wave solutions and dynamical behavior of nonlinear low-pass electrical models in the fractional framework [PDF]

open access: yesScientific Reports
The paper is an analytical study of a low-pass electrical model of nonlinear type in a fractional perspective, in which the classical derivative is generalized to the Katugampola fractional operator. Precise traveling-wave solutions are built based on an

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

open access: yesDiscrete and Continuous Dynamical Systems, 2007
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.

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

open access: yesStudies in Applied Mathematics, 2021
AbstractWe study a family of monic orthogonal polynomials that are orthogonal with respect to the varying, complex‐valued weight function, , over the interval , where is arbitrary. This family of polynomials originally appeared in the literature when the parameter was purely imaginary, that is, , due to its connection with complex Gaussian quadrature ...

Global phase portraits of a SIS model [PDF]

open access: yesApplied Mathematics and Computation, 2013
In the qualitative theory of ordinary differential equations, we can find many papers whose objective is the classification of all the possible topological phase portraits of a given family of differential system. Most of the studies rely on systems with real parameters and the study consists of outlining their phase portraits by finding out some ...

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

open access: yesNonlinear 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.
