Solution of High-Order Nonlinear Integrable Systems Using Darboux Transformation

open access: yesAxioms, 2023
The 4×4 trace-free complex matrix set is introduced in this study. By using it, we are able to create a novel soliton hierarchy that is reduced to demonstrate its bi-Hamiltonian structure.

Darboux transformation of symmetric Jacobi matrices and Toda lattices [PDF]

open access: yesFrontiers in Applied Mathematics and Statistics
Let J be a symmetric Jacobi matrix associated with some Toda lattice. We find conditions for Jacobi matrix J to admit factorization J = LU (or J = 𝔘𝔏) with L (or 𝔏) and U (or 𝔘) being lower and upper triangular two-diagonal matrices, respectively.

A Family of Integrable Different-Difference Equations, Its Hamiltonian Structure, and Darboux-Bäcklund Transformation

open access: yesDiscrete Dynamics in Nature and Society, 2018
An integrable family of the different-difference equations is derived from a discrete matrix spectral problem by the discrete zero curvature representation. Hamiltonian structure of obtained integrable family is established.

Darboux transformation and solution of the modified Korteweg–de Vries equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2015
Darboux transformation and a comprehensive approach to construct exact solutions of the nonlinear differential equation are counted. It is applied to construct the explicit solutions of the (2+1)-dimensional modified Korteweg-de Vries (KdV) equation. In

A modified Suris hierarchy and N-fold Darboux -Bäcklund transformation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
A modified Suris hierarchy is derived by discrete zero curvature equation. Bi-Hamiltonian structure of the whole hierarchy is established through the discrete trace identity. And we prove that the obtained hierarchy is Liouville integrable.

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 ...

Darboux transformation and exact solutions for a four-component Fokas–Lenells equation

open access: yesResults in Physics, 2021
In the present paper, we introduce a 4 × 4 matrix spectral problem and derive a four-component Fokas–Lenells equation. N-fold Darboux transformations for the four-component Fokas–Lenells equation are constructed by using the gauge transformation between ...

A unified approach to Darboux transformations [PDF]

open access: yesInverse Problems, 2009
We analyze a certain class of integral equations related to Marchenko equations and Gel'fand-Levitan equations associated with various systems of ordinary differential operators. When the integral operator is perturbed by a finite-rank perturbation, we explicitly evaluate the change in the solution.
