Darboux transformations and rogue wave solutions of a generalized AB system for the geophysical flows

open access: yesApplied Mathematics Letters, 2019
In this paper, we investigate a generalized AB system, which is used to describe certain baroclinic instability processes in the geophysical flows. For the two short waves and mean flow, we derive out the Darboux and generalized Darboux transformations ...

Darboux transformations and global solutions for a nonlocal derivative nonlinear Schrödinger equation [PDF]

open access: yesCommunications in nonlinear science & numerical simulation, 2016
A nonlocal derivative nonlinear Schrodinger equation is discussed. By constructing its Darboux transformations of degree 2n, the explicit expressions of new solutions are derived from zero seed solutions.

The Darboux system: Finite-rank constraints and Darboux transformations [PDF]

open access: yesJournal of Mathematical Physics, 1997
The exponential solutions of the Darboux equations for conjugate nets is considered. It is shown that rank-one constraints over the right derivatives of invertible operators on an arbitrary linear space give solutions of the Darboux system, which can be understood as a vectorial Darboux transformation of the exponential background.

A Comprehensive Study of the Complex mKdV Equation through the Singular Manifold Method

open access: yesMathematics, 2023
In this paper, we introduce a modification of the Singular Manifold Method in order to derive the associated spectral problem for a generalization of the complex version of the modified Korteweg–de Vries equation.

Darboux Transformations for Supersymmetric Korteweg - de Vries Equations [PDF]

open access: yes, 1994
\hspace{.2in}We consider the Darboux type transformations for the spectral problems of supersymmetric KdV systems. The supersymmetric analogies of Darboux and Darboux-Levi transformations are established for the spectral problems of Manin-Radul-Mathieu ...

Darboux-type transformations and hyperelliptic curves [PDF]

open access: greenJournal für die reine und angewandte Mathematik (Crelles Journal), 1999
We systematically study Darboux-type transformations for the KdV and AKNS hierarchies and provide a complete account of their effects on hyperelliptic curves associated with algebro-geometric solutions of these hierarchies.

Darboux transformation: new identities [PDF]

open access: yesPhysica Scripta, 2019
This letter reports some new identities for multisoliton potentials that are based on the explicit representation provided by the Darboux matrix. These identities can be used to compute the complex gradient of the energy content of the tail of the profile with respect to the discrete eigenvalues and the norming constants. The associated derivatives are

B\"acklund-Darboux Transformations and Discretizations of Super KdV Equation [PDF]

open access: yes, 2014
For a generalized super KdV equation, three Darboux transformations and the corresponding B\"acklund transformations are constructed. The compatibility of these Darboux transformations leads to three discrete systems and their Lax representations.

A look at the generalized Darboux transformations for the quasinormal spectra in Schwarzschild black hole perturbation theory: Just how general should it be? [PDF]

open access: yesPhysics Letters, 2018
In this article we take a close look at three types of transformations usable in the Schwarzschild black hole perturbation theory: a standard (DT), a binary (BDT) and a generalized (GDT) Darboux transformations.

Quantum reference frames: derivation of perspective-dependent descriptions via a perspective-neutral structure [PDF]

open access: yesQuantum, 2023
In standard quantum mechanics, reference frames are treated as abstract entities. We can think of them as idealized, infinite-mass subsystems which decouple from the rest of the system. In nature, however, all reference frames are realized through finite-
