The sine-Gordon model is a ubiquitous model of Mathematical Physics with a wide range of
applications extending from coupled torsion pendula and Josephson junction arrays to
gravitational and high-energy physics models. The purpose of this book is to present a summary
of recent developments in this field incorporating both introductory background material but
also with a strong view towards modern applications recent experiments developments regarding
the existence stability dynamics and asymptotics of nonlinear waves that arise in the model.
This book is of particular interest to a wide range of researchers in this field but serves as
an introductory text for young researchers and students interested in the topic. The book
consists of well-selected thematic chapters on diverse mathematical and physical aspects of the
equation carefully chosen and assigned.
