A Robust Inverse Scattering Transform for the Focusing Nonlinear Schrödinger Equation [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2017
We propose a modification of the standard inverse scattering transform for the focusing nonlinear Schrödinger equation (also other equations by natural generalization) formulated with nonzero boundary conditions at infinity.

Integration of the Loaded Negative Order Nonlinear Schrodinger Equation in the Class of Periodic Functions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
In this paper, we consider the loaded negative order nonlinear Schrodinger equation (NSE) in the class of periodic functions. It is shown that the loaded negative order nonlinear Schrodinger equation can be integrated by the inverse spectral problem ...

Semiclassical stationary states for nonlinear Schr\"odinger equations under a strong external magnetic field [PDF]

open access: yes, 2015
We construct solutions to the nonlinear magnetic Schr\"odinger equation $$ \left\{ \begin{aligned} - \varepsilon^2 \Delta_{A/\varepsilon^2} u + V u &= \lvert u\rvert^{p-2} u & &\text{in}\ \Omega,\\ u &= 0 & &\text{on}\ \partial\Omega, \end{aligned}

Multiscale theory of nonlinear wavepacket propagation in a planar optical waveguide [PDF]

open access: yes, 2002
In this paper, the multiscale expansion formalism is applied for the first time, to our knowledge, in nonlinear planar optical waveguides. This formalism permits us to describe the linear and nonlinear propagation for both transverse electric and ...
