Invertible Darboux Transformations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
For operators of many different kinds it has been proved that (generalized) Darboux transformations can be built using so called Wronskian formulae.

Darboux Integrals for Schrödinger Planar Vector Fields via Darboux Transformations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
In this paper we study the Darboux transformations of planar vector fields of Schrödinger type. Using the isogaloisian property of Darboux transformation we prove the ''invariance'' of the objects of the ''Darboux theory of integrability''. In particular,

Soliton Solutions to Sasa–Satsuma-Type Modified Korteweg–De Vries Equations by Binary Darboux Transformations

open access: yesMathematics
Sasa–Satsuma (SS)-type integrable matrix modified Korteweg–de Vries (mKdV) equations are derived from two group constraints, involving the replacement of the spectral matrix in the Ablowitz–Kaup–Newell–Segur matrix eigenproblems with its matrix transpose

Miura and Darboux transformations in the SUSY KP hierarchies

open access: yesNuclear Physics B, 2022
The Miura links between the KP and modified KP hierarchies are extended to the SUSY KP (SKP) and SUSY modified KP hierarchies (SmKP) of Manin Radul and Jacobian types.

Construction of angular-dependent potentials from trigonometric Pöschl-Teller systems within the Dunkl formalism

open access: yesActa Polytechnica, 2023
We generate solvable cases of the two angular equations resulting from variable separation in the three-dimensional Dunkl-Schrödinger equation expressed in spherical coordinates.

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 ...

Explicit solutions of rational integrable differential-difference equations

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The rational integrable differential-difference equations are proposed from a different discrete spectral problem. We proved the Liouville integrability of rational integrable differential-difference equations by deriving its bi-Hamiltonian structures ...
