Lagrangian and Hamiltonian structures in an integrable hierarchy and space–time duality

open access: yesNuclear Physics B, 2016
We define and illustrate the novel notion of dual integrable hierarchies, on the example of the nonlinear Schrödinger (NLS) hierarchy. For each integrable nonlinear evolution equation (NLEE) in the hierarchy, dual integrable structures are characterized ...

NONLINEAR EQUATION WITH THE THIRD ORDER SCATTERING OPERATOR

open access: yesНаука. Инновации. Технологии, 2022
Introduction: most of the differential equations associated with soliton mathematics are obtained using the Lax operator equation or the zero-curvature equation, which are the compatibility condition for a pair of linear differential systems. The case in

The Lax pairs for the Holt system [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1999
By using non-canonical transformation between the Holt system and the Henon-Heiles system the Lax pairs for all the integrable cases of the Holt system are constructed from the known Lax representations for the Henon-Heiles system.

Weak Lax pairs for lattice equations [PDF]

open access: yesNonlinearity, 2012
We consider various 2D lattice equations and their integrability, from the point of view of 3D consistency, Lax pairs and Bäcklund transformations. We show that these concepts, which are associated with integrability, are not strictly equivalent. In the course of our analysis, we introduce a number of black and white lattice models, as well as variants

Symmetries for the Semi-Discrete Lattice Potential Korteweg–de Vries Equation

open access: yesMathematics
In this paper, we prove that the isospectral flows associated with both the x-part and the n-part of the Lax pair of the semi-discrete lattice potential Korteweg–de Vries equation are symmetries of the equation.

Notes on “Soliton solutions by Darboux transformation and some reductions for a new Hamiltonian lattice hierarchy” [Phys. Scr. 82 (2010) 015008]

open access: yesResults in Physics, 2016
We demonstrate that the Darboux transformation in the paper “Soliton solutions by Darboux transformation and some reductions for a new Hamiltonian lattice hierarchy” [Phys. Scr.

On some integrability aspects of the two-component Camassa–Holm equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The integrability of the two-component Camassa–Holm shallow water equation with the gravity acceleration points downwards and upwards is investigated by prolongation structure theory and the geometric approach of pseudo-spherical surfaces.

Lax pairs for deformed Minkowski spacetimes [PDF]

open access: yesJournal of High Energy Physics, 2016
We proceed to study Yang-Baxter deformations of 4D Minkowski spacetime based on a conformal embedding. We first revisit a Melvin background and argue a Lax pair by adopting a simple replacement law invented in 1509.00173. This argument enables us to deduce a general expression of Lax pair.

On the complete integrability of an equation having solitons but not known to have a Lax pair

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
It is usually assumed that a system having N-soliton solutions is completely integrable. Here we have analyzed a set of equations occuring in case of capillary gravity waves.
