Preface

The subject of chaos theory has passed from the domain of scientific research to the general domain of interest among non-scientists. It is not unusual to hear of the subject of chaos discussed by professional scientists and laymen alike. It is well known that the subject touches on diverse areas such as population dynamics, the study of climates and weather, chaos in atoms and chemical reaction physics, and the subject of quantum chaos.

The current volume presents 12 very interesting contributions to this active area of research. One of the main contributions of the book is to illustrate the wide diversity of subjects that this area of research impacts. The papers themselves range over a wide collection of topics such as chaos and complex dynamics, several papers on nonlinear dynamics, another on quantum integrability, a paper that pertains to the Covid epidemic, chaotic behavior of ICT users, and as well as 3 papers related to perturbation theory and chaos.

The book has been assembled out of the hard work of an international group of invited authors. It is a pleasure to thank them for their efforts and scientific contributions. The editors are also grateful to acknowledge with much thanks to the continuous support and assistance of Mr. Josip Knapić, Author Services Manager, as well as the IntechOpen publishing group for the opportunity to participate in the assembly of this collection of papers.
