Existence of integrable solutions for integro-differential inclusions of fractional order; coupled system approach

open access: yes, 2020
In this article, we establish the existence of solutions for a functional integral equation of fractional order. The study upholds the case when the set-valued function has L1-Carathèodory selections, we reformulate the functional integral inclusion ...

The stability of bright–dark solitons in defocusing coupled nonlinear Schrödinger equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The Darboux transformation is a classical method to generate the solitonic solutions for the integrable equations. In this work, we develop the Darboux transformation to analyze the spectral stability of bright–dark soliton for defocusing coupled ...

Integrable structure of BCD conformal field theory and boundary Bethe ansatz for affine Yangian

open access: yesJournal of High Energy Physics, 2021
In these notes we study integrable structures of conformal field theory with BCD symmetry. We realise these integrable structures as gl $$ \mathfrak{gl} $$ (1) affine Yangian “spin chains” with boundaries.

A New Discrete Integrable System Derived from a Generalized Ablowitz-Ladik Hierarchy and Its Darboux Transformation

open access: yesDiscrete Dynamics in Nature and Society, 2012
We find an interesting phenomenon that the discrete system appearing in a reference can be reduced to the old integrable system given by Merola, Ragnisco, and Tu in another reference.

The generalized dressing method with applications to the integration of variable-coefficient Toda equations; pp. 93–98 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2010
Integrable variable-coefficient 2D Toda lattice equations are proposed by utilizing a generalized version of the dressing method. Compatibility conditions are given, which ensures that these equations are integrable.

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.
