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.

Binary Bell polynomials and Darboux covariant Lax pairs [PDF]

open access: yesGlasgow Mathematical Journal, 2001
Hirota representations of soliton equations have proved very useful. They produced many of the known families of multisoliton solutions, and have often led to a disclosure of the underlying Lax systems and infinite sets of conserved quantities. A striking feature is the ease with which direct insight can be gained into the nature of the eigenvalue ...

Simplifications of Lax pairs for differential–difference equations by gauge transformations and (doubly) modified integrable equations

open access: yesPartial Differential Equations in Applied Mathematics
Matrix differential–difference Lax pairs play an essential role in the theory of integrable nonlinear differential–difference equations. We present sufficient conditions which allow one to simplify such a Lax pair by matrix gauge transformations ...

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.

The N-soliton solutions of the n-component generalized Sasa-Satsuma system: Riemann-Hilbert method

open access: yesNuclear Physics B
Using the Riemann-Hilbert method, the paper systematically investigates the n-component generalized Sasa-Satsuma system. By utilizing the Tu scheme, we systematically construct the n-component generalized Sasa-Satsuma integrable hierarchy, and obtain the

Generalised Born-Infeld models, Lax operators and the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ perturbation

open access: yesJournal of High Energy Physics, 2018
Surprising links between the deformation of 2D quantum field theories induced by the composite T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator, effective string models and the AdS/CFT correspondence, have recently emerged.

The N-soliton solutions to the M-components nonlinear Schrödinger equations by the Riemann–Hilbert approach

open access: yesPartial Differential Equations in Applied Mathematics, 2022
In this paper, the main work is to study the N-soliton solutions for the M-component nonlinear Schrödinger equations, the matrix Riemann–Hilbert problem is constructed for this integrable hierarchies by analyzing the block matrix spectral problem of the ...

Lax pairs on Yang-Baxter deformed backgrounds [PDF]

open access: yes, 2015
We explicitly derive Lax pairs for string theories on Yang-Baxter deformed backgrounds, 1) gravity duals for noncommutative gauge theories, 2) $\gamma$-deformations of S$^5$, 3) Schr\"odinger spacetimes and 4) abelian twists of the global AdS$_5$\,. Then
