This is a review of two of the fundamental tools for analysis of soliton equations: i) the algebraic ones based on Kac-Moody algebras, their central extensions and their dual algebras which underlie the Hamiltonian structures of the NLEE; ii) the construction of the fundamental analytic solutions of the Lax operator and the Riemann-Hilbert problem (RHP) which they satisfy. The fact that the inverse scattering problem for the Lax operator can be viewed as a RHP gave rise to the dressing Zakharov…

Basic Aspects of Soliton Theory
This is a review of the main ideas of the inverse scattering method (ISM) for solving nonlinear evolution equations (NLEE), known as soliton equations. As a basic tool we use the fundamental analytic
BREATHER SOLUTIONS OF A -WAVE EQUATIONS
, We consider A-wave type equations related to symplectic and or­ thogonal algebras. We obtain their soliton solutions in the case when two different Z2 reductions (or equivalently one Z2 v Z2
Nonlocal Reductions of The Multicomponent Nonlinear Schrödinger Equation on Symmetric Spaces
Our aim is to develop the inverse scattering transform for multicomponent generalizations of nonlocal reductions of the nonlinear Schrödinger (NLS) equation with $$\mathcal{PT}$$PT symmetry related
On the stability of N-solitons in integrable systems
The dynamical stability of reflectionless N-solitons for a large class of integrable systems is considered. The underlying eigenvalue problem is the Zakharov–Shabat problem on for any r ≥ 1. Physical
Two-dimensional Toda field equations related to the exceptional algebra $\mathfrak{g}_2 $: Spectral properties of the lax operators
We analyze spectral properties of the Lax operator corresponding to the two-dimensional Toda field equations related to the algebra $\mathfrak{g}_2 $. We construct two minimal sets of scattering data
The Multicomponent Higher-Order Chen–Lee–Liu System: The Riemann–Hilbert Problem and Its N-Soliton Solution
It is well known that multicomponent integrable systems provide a method for analyzing phenomena with numerous interactions, due to the interactions between their different components. In this paper,
Algebro-geometric Solutions for the Degasperis-Procesi Hierarchy
TLDR
A third order algebraic curve is introduced with characteristic polynomial of a Lax matrix for the DP hierarchy, from which the associated Baker--Akhiezer functions, meromorphic function and Dubrovin-type equations are established.
