Invertible Darboux Transformations [PDF]
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]
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,

An one-fold Darboux transformation for the Lotka–Volterra lattice system is first established using a proper gauge transformation matrix. Then, as a result of the N times one-fold Darboux transformation, the corresponding N-fold Darboux transformation of

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

Darboux transforms of Dupin surfaces [PDF]
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 ...

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