Scaling solutions in quintessential inflation

European Physical Journal C: Particles and Fields, 2020
In quintessence scalar field theories, the presence of scaling solutions are important during the radiation and matter epoch due to having their attractor character.

Basins of attraction of chimera states on networks

Frontiers in Physiology, 2022
Networks of identical coupled oscillators display a remarkable spatiotemporal pattern, the chimera state, where coherent oscillations coexist with incoherent ones. In this paper we show quantitatively in terms of basin stability that stable and breathing chimera states in the original two coupled networks typically have very small basins of attraction.

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

Advanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Basin of Attraction through Invariant Curves and Dominant Functions

Discrete Dynamics in Nature and Society, 2015
We study a second-order difference equation of the form zn+1=znF(zn-1)+h, where both F(z) and zF(z) are decreasing. We consider a set of invariant curves at h=1 and use it to characterize the behaviour of solutions when h>1 and when ...

Modified Potra-Pták Multi-step Schemes with Accelerated Order of Convergence for Solving Systems of Nonlinear Equations

Mathematical and Computational Applications, 2018
In this study, an iterative scheme of sixth order of convergence for solving systems of nonlinear equations is presented. The scheme is composed of three steps, of which the first two steps are that of third order Potra-Pták method and last is ...

Experimental definition of the basin of attraction for Chua's circuit

, 2000
In this paper we study the experimental determination of the basin of attraction for the Chua's circuit by means of an electronic device that is able to select initial voltages and to show the early stages of the subsequent trajectory on the oscilloscope.
