MODIFIED SCATTERING FOR THE CUBIC SCHRÖDINGER EQUATION ON PRODUCT SPACES AND APPLICATIONS

open access: yesForum of Mathematics, Pi, 2015
We consider the cubic nonlinear Schrödinger equation posed on the spatial domain $\mathbb{R}\times \mathbb{T}^{d}$. We prove modified scattering and construct modified wave operators for small initial and final data respectively ($1\leqslant d\leqslant 4$

On Classification of Integrable Davey-Stewartson Type Equations [PDF]

open access: yes, 2013
This paper is devoted to the classification of integrable Davey-Stewartson type equations. A list of potentially deformable dispersionless systems is obtained through the requirement that such systems must be generated by a polynomial dispersionless Lax ...

On an infinite sequence of invariant measures for the cubic nonlinear Schrödinger equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 7, Page 375-394, 2001., 2001
We consider the Cauchy problem periodic in the spatial variable for the usual cubic nonlinear Schrödinger equation and construct an infinite sequence of invariant measures associated with higher conservation laws for dynamical systems generated by this problem on appropriate phase spaces.

Stability of solitary-wave solutions of coupled NLS equations with power-type nonlinearities

open access: yesAdvances in Nonlinear Analysis, 2015
This paper proves existence and stability of solitary-wave solutions of a system of 2-coupled nonlinear Schrödinger equations with power-type nonlinearities arising in several models of modern physics. The existence of vector solitary-wave solutions (i.e.

On the method of pseudopotential for Schrödinger equation with nonlocal boundary conditions

open access: yesAbstract and Applied Analysis, Volume 6, Issue 6, Page 329-338, 2001., 2001
For stationary Schrödinger equation in ℝ n with the finite potential the singular pseudopotential is constructed in the form allowing us to find wave functions. The method does not require the knowledge of the explicit form of a potential and assumes only knowledge of the scattering amplitude for fixed level of energy.

Attractors of semigroups associated with nonlinear systems for diffusive phase separation

open access: yesAbstract and Applied Analysis, Volume 1, Issue 2, Page 169-192, 1996., 1996
We consider a model for diffusive phase transitions, for instance, the component separation in a binary mixture. Our model is described by two functions, the absolutete temperature θ : = θ(t, x) and the order parameter w : = w(t, x), which are governed by a system of two nonlinear parabolic PDEs.

On the derivation of the wave kinetic equation for NLS

open access: yesForum of Mathematics, Pi, 2021
A fundamental question in wave turbulence theory is to understand how the wave kinetic equation describes the long-time dynamics of its associated nonlinear dispersive equation.

Blow-up for self-interacting fractional Ginzburg-Landau equation

open access: yes, 2017
The blow-up of solutions for the Cauchy problem of fractional Ginzburg-Landau equation with non-positive nonlinearity is shown by an ODE argument. Moreover, in one dimensional case, the optimal lifespan estimate for size of initial data is obtained ...
