Encryption of Color Images Based on Chaotic Attractors Generated by ODE Systems Containing Module Nonlinearities

open access: yesJournal of Optimization, Differential Equations and Their Applications
The main objective of this work is to construct an algorithm for modeling chaotic attractors using special neural ODEs with antisymmetric matrices (antisymmetric neural ODEs) and modular power nonlinearities.

Tightening Poincaré–Bendixson theory after counting separately the fixed points on the boundary and interior of a planar region

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
This paper tightens the classical Poincaré–Bendixson theory for a positively invariant, simply-connected compact set $\mathcal M$ in a continuously differentiable planar vector field by further characterizing for any point $p\in \mathcal M$, the ...

Some remarks on the Melnikov function

open access: yesElectronic Journal of Differential Equations, 2002
We study the Melnikov function associated with a periodic perturbation of a differential equation having a homoclinic orbit. Our main interest is the characterization of perturbations that give rise to vanishing or non-vanishing of the Melnikov function.
