Analysis of a class of Lotka--Volterra systems
G. Moza, D. Constantinescu, R. Efrem +2
A generalized two-dimensional cubic Lotka-Volterra model with infinitesimal parameters is studied. Three different cases have been considered, one non-degenerate and two degenerate…
Fractional Transport in Strongly Turbulent Plasmas
Heinz Isliker, Loukas Vlahos, Dana Constantinescu
We analyze statistically the energization of particles in a large scale environment of strong turbulence that is fragmented into a large number of distributed current filaments. Th…
Anticontrol Techniques for Systems of Lorenz Type
Dana Constantinescu
The paper investigates some basic dynamical properties of a general system obtained from the Lorenz system using a non-linear feedback controller. We focus on the bifurcation of th…
Study of the interplay between magnetic shear and resonances using Hamiltonian models for the magnetic field lines
Marie-Christine Firpo, Dana Constantinescu
The issue of magnetic confinement in magnetic fusion devices is addressed within a purely magnetic approach. Using some Hamiltonian models for the magnetic field lines, the dual im…
