The E-mail message field is required. First, a demonstration is given of how discrete nonlinear integrable equations can be derived starting from their linear counterparts. An extensive treatment of the class of algebro-geometric solutions in the stationary as well as time-dependent contexts is provided. The book uses techniques from the theory of differential equations, spectral analysis, and elements of algebraic geometry most notably, the theory of compact Riemann surfaces. Algebraic Curves and Their Theta Functions in a Nutshell; B. The presentation is rigorous, detailed, and self-contained, with ample background material provided in various appendices. We also consider the continuous symmetries of the related equations and the related spectral curves.

A discrete analog of the dressing method is presented and used to derive integrable nonlinear evolution equations, including two infinite families of novel continuous and discrete coupled integrable systems of equations of nonlinear SchrĂ¶dinger type. Detailed notes for each chapter together with an exhaustive bibliography enhance the presentation offered in the main text. The book uses basic techniques from the theory of difference equations and spectral analysis, some elements of algebraic geometry and especially, the theory of compact Riemann surfaces. To make our method fully effective, we design a symbolic algorithm to compute the integration constants of the KdV hierarchy, in the case of KdV potentials that become rational under a Hamiltonian change of variable. As we all know, the hyperelliptic curve has an important application in the derivation of the quasi-periodic solution to the integrable systems associated with the 2 Ă 2 matrix spectral problems, such as the KdV, nonlinear SchrĂ¶dinger, mKdV, sine-Gordon, Camassa-Holm, Toda lattice, and Ablowitz-Ladik equations, etc.

The book uses basic techniques from the theory of difference equations and spectral analysis, some elements of algebraic geometry and especially, the theory of compact Riemann surfaces. As a result, an algebraicâgeometric solution in Riemann theta function of the hierarchy is obtained. Reviews of Volume 1: '. The presentation is constructive and rigorous, with ample background material provided in various appendices. The Kacvan Moerbeke hierarchy; 3. Volume I, 1 + 1 -dimensional continuous models.

Based on the Lenard recursion equation, Lax pair of the hierarchy is given. A specific reduction of the multicomponent mKdV system is made, together with its reduced Lax pair and soliton solutions. The systems studied in this volume include the Toda lattice hierarchy, the Kac-van Moerbeke hierarchy, and the Ablowitz- As a partner to Volume 1: Dimensional Continuous Models, this monograph provides a self-contained introduction to algebro-geometric solutions of completely integrable, nonlinear, partial differential-difference equations, also known as soliton equations. Hyperelliptic Curves of the Toda-Type; C. The book uses techniques from the theory of differential equations, spectral analysis, and elements of algebraic geometry most notably, the theory of compact Riemann surfaces. Any expert as well would enjoy the book and learn something stimulating from the sidenotes that point to alternative developments. We look forward to volumes two and three! Detailed notes for each chapter together with an exhaustive bibliography enhance the presentation offered in the main text.

The presentation is rigorous, detailed, and self-contained, with ample background material provided in various appendices. The formalism presented includes trace formulas, Dubrovin-type initial value problems, Baker-Akhiezer functions, and theta function representations of all relevant quantities involved. . The corresponding compatible vector reductions admitted by these systems are also discussed, as well as their continuum limits. Besides, two equations, the Volterra lattice and a 2+1 -dimensional Burgers equation with a discrete variable, yielded from the hierarchy are also solved.

Uncovering such structure in the attempt at finding defining properties of, and tests for, integrability brought to light new mathematical constructions which span classical to futuristic interdisciplinary areas. Differential resultants are used for computing spectral curves, and differential subresultants to obtain the first order common factor. The list of inverse Sumudu transforms is added in the sequel to strengthen the study. Detailed notes for each chapter, together with an exhaustive bibliography, enhance understanding of the main results.

The theory presented includes trace formulas, algebro-geometric initial value problems, Baker-Akhiezer functions, and theta function representations of all relevant quantities involved. The focus of this book is on algebro-geometric solutions of completely integrable nonlinear partial differential equations in 1+1 -dimensions, also known as soliton equations. The two new sets of exact analytical and complex solutions are gotten through a discrete inverse Sumudu transform, and Maple complex graphs are drawn to show the new solution simulations in the complex plane which are compared to the existing solutions. As a partner to Volume 1: Dimensional Continuous Models, this monograph provides a self-contained introduction to algebro-geometric solutions of completely integrable, nonlinear, partial differential-difference equations, also known as soliton equations.

They are used to study the Cauchy problem for the Kortewegâde Vries equation. We derive a zero-curvature formalism for a combined sine-Gordon sG and modified Korteweg-de Vries mKdV equation which yields a local sGmKdV hierarchy. The formalism presented includes trace formulas, Dubrovin-type initial value problems, Baker-Akhiezer functions, and theta function representations of all relevant quantities involved. Johanna Michor is a Postdoctoral Fellow in the Faculty of Mathematics at the University of Vienna. The trace-class property of Hankel operators and their derivatives with respect to the parameter with strongly oscillating symbol is studied. Further, the discrete spectral problem is nonlinearized into an integrable symplectic map. An extensive treatment of the class of algebro-geometric solutions in the stationary as well as time-dependent contexts is provided.
