Dynamical Systems

Orlando, Giuseppe; Taglialatela, Giovanni - In: Nonlinearities in economics : an interdisciplinary …, (pp. 13-37). 2021

In this Chapter, we provide the definitions, notions and examples relevant for the analysis of the dynamical systems of interest to us in the remainder of this book. We start with with a description of dynamical systems and we provide a taxonomy. Then, we define continuous-time dynamical systems...

Cryptanalysis and Improvement of a Digital Watermarking Scheme Using Chaotic Map

Ahmad, Musheer; AlSharari, Hamed D. - In: International Journal of Rough Sets and Data Analysis … 5 (2018) 4, pp. 61-73

In the recent past, a new statistically efficient digital image watermarking scheme based on chaotic map was proposed. The authors of this watermarking scheme claimed under study that their scheme is efficient, secure, and highly robust against various attacks. However, the security analysis of...

Forecasting chaotic systems : the role of local Lyapunov exponents.

Guegan, Dominique; Leroux, Justin - Centre d'Économie de la Sorbonne, Université Paris 1 … - 2008

We propose a novel methodology for forecasting chaotic systems which is based on the nearest-neighbor predictor and improves upon it by incorporating local Lyapunov exponents to correct for its inevitable bias. Using simulated data, we show that gains in prediction accuracy can be substantial....

Una rassegna su alcuni modelli di crescita economica tipo Solow con dinamica caotica

Palmisani, Cesare - Volkswirtschaftliche Fakultät, … - 2008

In this paper we review some Solow-type growth models, framed is discrete time, which are able to generate complex dynamic behaviour. For these models put forward by Day (1982, 1983); Böhm and Kaas (2000); and Commendatore (2005) we show that crucial features which could determine the emergence...
