Slow invariant manifolds as curvature of the flow of dynamical systems [PDF]
, 2014 Considering trajectory curves, integral of n-dimensional dynamical systems, within the framework of Differential Geometry as curves in Euclidean n-space, it will be established in this article that the curvature of the flow, i.e.

Characterisation of Singular Domains in Threshold-Dependent Biological Networks
Journal of Nigerian Society of Physical Sciences, 2022 Threshold-dependent networks behave like piecewise smooth system which belongs to a class of systems with discontinuous right hand side. It can be studied with piecewise linear differential equations.

Limit cycles of piecewise differential systems with linear Hamiltonian saddles and linear centres
Dynamical Systems, 2022 We study the continuous and discontinuous planar piecewise differential systems formed by linear centres together with linear Hamiltonian saddles separated by one or two parallel straight lines. When these piecewise differential systems are either continuous or discontinuous separated by one straight line, they have no limit cycles.

Mathematical Analisys of a Third-order Memristor-based Chua's Oscillator
Trends in Computational and Applied Mathematics, 2011 . In this paper we present a detailed linear analysis of the equilibrium points stability of a memristor oscillator mathematical model, given by a threedimensional 5-parameter piecewise-linear system of ordinary differential equations.

Limit Cycles for Piecewise Linear Differential Systems via Poincaré–Miranda Theorem [PDF]
, 2019 In Gasull and Mañosa (Periodic orbits of discrete and continuous dynamical systems via Poincaré–Miranda theorem, Preprint 2018 Ref [2]), we develop an effective procedure to prove the existence, determine the number, and locate periodic orbits of dynamical systems of both discrete and continuous nature.

Generation of Multistability through Unstable Systems
Chaos Theory and Applications, 2022 In this work, we propose an approach to generate multistability based on a class of unstable systems that have all their roots in the right complex half-plane.

Convergence Analysis of Cubic Spline Function with Fractional Degree and Applications [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2023 In this paper, a fractional degree cubic spline scheme is proposed and analyzed for fractional order with the multi-term Riemann–Liouvile (R–L) derivatives. For the integral and fractional differential equations, we handle fractional continuity equations

On a differential inclusion related to the Born-Infeld equations [PDF]
, 2013 We study a partial differential relation that arises in the context of the Born-Infeld equations (an extension of the Maxwell's equations) by using Gromov's method of convex integration in the setting of divergence free ...
