Discrete Lagrangian Models
These lectures are devoted to discrete integrable Lagrangian models. A large collection of integrable models is presented in the Lagrangian fashion,... -
Discrete Differential Geometry. Integrability as Consistency
We discuss a new geometric approach to discrete integrability coming from discrete differential geometry. A d–dimensional equation is called... -
Special Solutions for Discrete Painlevé Equations
We construct special solutions for the discrete Painlevé equations. We start with a review of the corresponding solutions in the case of the... -
Analytic and Asymptotic Methods for Nonlinear Singularity Analysis: A Review and Extensions of Tests for the Painlevé Property
The integrability (solvability via an associated single-valued linear problem) of a differential equation is closely related to the singularity... -
Special Solutions of Discrete Integrable Systems
Hierarchies of discrete soliton equations are constructed in bilinear form as a consequence of the algebraic identities satisfied by determinants and... -

The method of Poisson pairs in the theory of nonlinear PDEs
The aim of these lectures is to show that the methods of classical Hamiltonian mechanics can be profitably used to solve certain classes of nonlinear... -
Lie groups, singularities and solutions of nonlinear partial differential equations
It is shown how Lie group and Lie algebra theory can be used to solve partial differential equations. A method for calculating the symmetry group of... -
Lie Bialgebras, Poisson Lie Groups, and Dressing Transformations
In this course, we present an elementary introduction, including the proofs of the main theorems, to the theory of Lie bialgebras and Poisson Lie... -
Eight Lectures on Integrable Systems
These lectures provide an introduction to the theory of integrable systems from the point of view of Poisson manifolds. In classical mechanics, an... -
Three Lessons on the Painlevé Property and the Painlevé Equations
While this school focuses on discrete integrable systems we feel it necessary, if only for reasons of comparison, to go back to fundamentals and... -
Introduction to the Hirota Bilinear Method
We give an elementary introduction to Hirota’s direct method of constructing multi-soliton solutions to integrable nonlinear evolution equations. We... -
Quantum and Classical Integrable Systems
The key concept discussed in these lectures is the relation between the Hamiltonians of a quantum integrable system and the Casimir elements in the... -
