PrefacePreface Κεφάλαιο σε Βιβλίο Book Chapter 2024-07-152022enThis book publishes proceedings of the 14th International Conference (CHAOS2021) on Chaotic Modeling, Simulation and Applications. We support the study of nonlinear systems and dynamics in an interdisciplinary research field, and very interesting applications were presented. We provide a widely selected forum to exchange ideas, methods and techniques in the field of nonlinear dynamics, chaos, fractals and their applications in general science and in engineering sciences. The principal aim of CHAOS2021 International Conference is to expand the development of the theories of the applied nonlinear field, the methods and the empirical data and computer techniques, and the best theoretical achievements of chaotic theory as well.http://creativecommons.org/licenses/by/4.0/Springer Proceedings in Complexity14th Chaotic Modeling and Simulation International Conference Skiadas Christos Σκιαδας Χρηστος Dimotikalis, Ioannis Springer Nature Non-linear dynamical systems Chaos theory Attractors and fractals Neural synchronisation
