Discrete Dynamical Models

Deploying a multi-disciplinary approach enabling a broad overview of the applications, this text includes stepwise exercises and worked solutions, introduces the notion of chaotic dynamics, and covers vector-valued discrete systems applied to Markov chains.

This book provides an introduction to the analysis of discrete dynamical systems. The content is presented by an unitary approach that blends the perspective of mathematical modeling together with the ones of several discipline as Mathematical Analysis, Linear Algebra, Numerical Analysis, Systems Theory and Probability. After a preliminary discussion of several models, the main tools for the study of linear and non-linear scalar dynamical systems are presented, paying particular attention to the stability analysis. Linear difference equations are studied in detail and an elementary introduction of Z and Discrete Fourier Transform is presented. A whole chapter is devoted to the study of bifurcations and chaotic dynamics. One-step vector-valued dynamical systems are the subject of three chapters, where the reader can find the applications to positive systems, Markov chains, networks and search engines. The book is addressed mainly to students in Mathematics, Engineering, Physics, Chemistry, Biology and Economics. The exposition is self-contained: some appendices present prerequisites, algorithms and suggestions for computer simulations. The analysis of several examples is enriched by the proposition of many related exercises of increasing difficulty; in the last chapter the detailed solution is given for most of them.

The multi-disciplinary and modellistic approach provides a broad overview of the applications A large number of step-by-step exercises and their worked solutions help the reader to learn quickly The notion of chaotic dynamics is introduced through an in-depth study of the logistic model Vector-valued discrete dynamical systems are focussed especially in connection to Markov chains, positive systems, demography and page-rank algorithm Includes supplementary material: sn.pub/extras
