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.

The multidimensional Darboux transformation [PDF]

open access: yesJournal of Geometry and Physics, 1998
A generalization of the classical one-dimensional Darboux transformation to arbitrary n-dimensional oriented Riemannian manifolds is constructed using an intrinsic formulation based on the properties of twisted Hodge Laplacians. The classical two-dimensional Moutard transformation is also generalized to non-compact oriented Riemannian manifolds of ...

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 ...

Yang–Baxter maps, Darboux transformations, and linear approximations of refactorisation problems [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2020
Yang–Baxter maps (YB maps) are set-theoretical solutions to the quantum Yang–Baxter equation. For a set X = Ω × V, where V is a vector space and Ω is regarded as a space of parameters, a linear parametric YB map is a YB map Y: X × X → X × X such that Y ...

Lax Representation and Darboux Solutions of the Classical Painlevé Second Equation

open access: yesAdvances in Mathematical Physics, 2021
In this article, we present Darboux solutions of the classical Painlevé second equation. We reexpress the classical Painlevé second Lax pair in new setting introducing gauge transformations to yield its Darboux expression in additive form. The new linear

Darboux transforms of Dupin surfaces [PDF]

open access: yesBanach Center Publications, 2002
We present a Mobius invariant construction of the Darboux transformation for isothermic surfaces by the method of moving frames and use it to give a complete classification of the Darboux transforms of Dupin ...

A Five-Component Generalized mKdV Equation and Its Exact Solutions

open access: yesMathematics, 2020
In this paper, a 3 × 3 spectral problem is proposed and a five-component equation that consists of two different mKdV equations is derived. A Darboux transformation of the five-component equation is presented relating to the gauge transformations

On a Vector Modified Yajima–Oikawa Long-Wave–Short-Wave Equation

open access: yesMathematics, 2019
A vector modified Yajima−Oikawa long-wave−short-wave equation is proposed using the zero-curvature presentation. On the basis of the Riccati equations associated with the Lax pair, a method is developed to construct multi-fold classical and ...

Darboux Transformations and Soliton-Like Solutions of a New System Associated with the Negative AKNS System

open access: yesAdvances in Mathematical Physics, 2022
In this letter, we consider a new two-component system. By its reciprocal relation with the first negative flow in the AKNS hierarchy, we construct three Darboux-Bäcklund transformations for the new system and obtain some soliton-like solutions.
