Nonlinear Systems and Their Remarkable Mathematical Structures: Volume 2

Nonlinear Systems and Their Remarkable Mathematical Structures, Volume 2 is written in a careful pedagogical manner by experts from the field of nonlinear differential equations and nonlinear dynamical systems (both continuous and discrete). This book aims to clearly illustrate the mathematical theories of nonlinear systems and its progress to both non-experts and active researchers in this area. Just like the first volume, this book is suitable for graduate students in mathematics, applied mathematics and engineering sciences, as well as for researchers in the subject of differential equations and dynamical systems. Features Collects contributions on recent advances in the subject of nonlinear systems Aims to make the advanced mathematical methods accessible to the non-experts Suitable for a broad readership including researchers and graduate students in mathematics and applied mathematics

Review :
"This is an excellent complement to the first volume, with a roster of authors including many of the best contributors to the major developments on dynamical systems of the last few decades." —Francesco Calogero, Emeritus Professor, University of Rome "La Sapienza" “This book contains useful introductory and review articles on several topics connected with integrability. Among others it includes four articles on various symmetry approaches, and a nice introduction to cluster algebras and integrability. I particularly liked the extensive reviews of elliptic difference Painleve equations, and of Wronskian solutions of integrable systems. With so many good review articles, it will serve as a nice reference book for anybody working with integrable systems.” —Emeritus Professor Jarmo Hietarinta, University of Turku “This volume is a sequel to a recently launched project of publishing invited contributions written by leading experts in the area of integrable systems and their applications. The content covers a wide range of topics, both classical and relatively recent. It provides a valuable source of information for both experts and the beginners. Various combinations of sections of the book would make excellent self-contained lecture courses. The material is grouped into 3 Parts: Part A: Integrability, Lax pairs and Symmetry (reciprocal transformations, contact Lax pairs and dispersionless systems, Lax pairs for Boussinesq systems, symmetries of delay differential equations, symmetry approach to integrability, classical and non-classical symmetries). Part B: Algebraic and Geometric Methods (instabilities of NLS plane waves, rational solutions to Painleve equations, cluster algebras and discrete integrability, elliptic difference Painleve equations, linkage mechanisms and discrete curves, Cauchy problems and infinite-dimensional groups, Wronskian solutions). Part C: Applications (gradient catastrophe in shallow water model, vibrations of an elastic bar and modified Camassa-Holm equations, exactly solvable quantum mechanics and orthogonal polynomials). This book will certainly be a valuable asset to any University library. Written by established and actively working researchers, it is quite unique in style due to the breath of the material covered. It will remain a valuable source of information for years to come.” —Professor E.V. Ferapontov, Loughborough University "This is the second in the pair of beautiful volumes casting a portrait of present day knowledge of nonlinear systems, with contributions by some of the leading experts in the field." —Professor Giuseppe Gaeta, Università di Milano
