Bifurcations in Globally Coupled Map Lattices
, 1994 The dynamics of globally coupled map lattices can be described in terms of a nonlinear Frobenius--Perron equation in the limit of large system size. This approach allows for an analytical computation of stationary states and their stability. The complete

International Journal of Bifurcation and Chaos, 2014 The onset and bifurcation points of n-cycles of several polynomial maps are located through a characteristic equation connecting cyclic polynomials of the cycle points. The polynomials satisfied by the parameters of the logistic, Hénon, and cubic maps at the onset and bifurcation points are obtained for n up to 14, 9, and 9, respectively.

Intrinsic noise and discrete-time processes
, 2013 A general formalism is developed to construct a Markov chain model that converges to a one-dimensional map in the infinite population limit. Stochastic fluctuations are therefore internal to the system and not externally specified. For finite populations

A Novel Image Encryption Scheme Based on Nonuniform Sampling in Block Compressive Sensing
IEEE Access, 2019 This paper devotes to the image compression and encryption problems. We develop a novel hybrid scheme based on block compressive sensing. Concentrate on taking full advantage of the different frequency coefficients sparsity, the nonuniform sampling ...

Computational information for the logistic map at the chaos threshold
, 2001 We study the logistic map $f(x)=\lambda x(1-x)$ on the unit square at the chaos threshold. By using the methods of symbolic dynamics, the information content of an orbit of a dynamical system is defined as the Algorithmic Information Content (AIC) of a ...

, 2021 This chapter is dedicated to discuss some dynamical properties of a generalized version of the logistic map called as logistic-like map. The fixed points and their stability are discussed as well as the convergence to the stationary state at and near at the bifurcations.

An Efficient Image Encryption Scheme Based on S-Boxes and Fractional-Order Differential Logistic Map
IEEE Access, 2020 In this work, an efficient image encryption based on S-boxes and fractional-order logistic map is proposed. The features of the fractional-order chaotic system in dynamical behaviors are exhibited.
