The recent economic crisis has led to an upswing in migration from the Mediterranean countries of Europe towards its central and northern development hubs. This overall increase in migration also includes high numbers of the so-called skilled migrant

In this paper we review several contributions made in the field of discrete dynamical systems, inspired by harmonic analysis. Within discrete dynamical systems, we focus exclusively on quadratic maps, both one-dimensional (1D) and two-dimensional (2D

This paper describes a method about how to determine parameters of some double-scroll chaotic systems, including the Lorenz system and the Chua s circuit, from one of its variables. The geometric properties of the system are exploited firstly to redu

In this work a conjecture to draw the bifurcation diagram of a map with multiple critical points is enunciated. The conjecture is checked by using two quartic maps in order to verify that the bifurcation diagrams obtained according to the conjecture

Harmonics give us a compact formula and a powerful tool in order to calculate the external arguments of the last appearance hyperbolic components and Misiurewicz points of the Mandelbrot set in some particular cases. Antiharmonics seem however to hav

In this work we present the alternated Julia sets, obtained by alternated iteration of two maps of the quadratic family [Formula: see text] and prove analytically and computationally that these sets can be connected, disconnected or totally disconnec

This paper studies the security of a chaotic cryptosystem based on Chua’s circuit and implemented with State Controlled Cellular Neural Networks (SC-CNN). Here we prove that the plaintext can be retrieved by bandpass filtering of the ciphertext or

Misiurewicz points are essential points of the Mandelbrot set. External arguments are the most useful tool in order to analyze these points; therefore, it is important to go deeper in the study of the external arguments' calculation of these points.
