The book "Solitons in Molecular Systems" explores the theory and applications of solitons in molecular systems. It is edited by M. Hazewinkel and includes contributions from leading scientists in mathematics and physics. The book discusses various aspects of solitons, including their properties, dynamics, and applications in molecular systems. It covers topics such as collective excitations in quasi-periodical molecular structures, solitons in molecular chains, and the dynamics of solitons in one-dimensional systems. The book also examines the role of solitons in biological systems, such as muscle contraction and electron transfer. It discusses the theory of solitons in molecular systems with nonlinear intermolecular interactions, and explores the applications of solitons in solid-state physics, including superconductivity and optical solitons. The book also covers the nonlinear sine-Gordon equation and its applications in superconductivity and other fields. The book is written for scientists and researchers in physics, biophysics, biochemistry, and mathematics. It provides a comprehensive overview of the theory and applications of solitons in molecular systems, and is an important contribution to the field of nonlinear dynamics and soliton theory.The book "Solitons in Molecular Systems" explores the theory and applications of solitons in molecular systems.
