On well-posedness of energy supercritical NLS on product space Rn×T4−n ${\mathbb{R}}^{n}{\times}{\mathbb{T}}^{4-n}$ (n = 0, 1, 2, 3)

open access: yesAdvances in Nonlinear Analysis
We establish the well-posedness theory for the quintic nonlinear Schrödinger equation (NLS) on four-dimensional tori (i.e., T4 ${\mathbb{T}}^{4}$ ), which is an energy-supercritical model. Compared to the recent breakthrough work (B. Kwak and S.

Dynamics And Bifurcations Of A Planar Map Modelling Dispersion Managed Breathers

open access: yes, 1997
. We study a non-autonomous ODE with piecewise-constant coefficients and its associated two-dimensional Poincar'e mapping. The ODE models variations in amplitude and phase of a pulse propagating in a lossless optical fiber with periodically varying ...

The Mechanism Of The Polarizational Mode Instability In Birefringent Fiber Optics

open access: yes, 2000
. We show the soliton solutions of the integrable Manakov equations exhibit an instability under arbitrarily small Hamiltonian perturbations. The instability arises from eigenvalues embedded in the essential spectrum of the associated linearized ...

Inviscid Limits of the Complex Ginzburg-Landau Equation

open access: yes, 2007
In the inviscid limit the generalized complex Ginzburg-Landau equation reduces to the nonlinear Schrodinger equation. This limit is proved rigorously with H 1 data in the whole space for the Cauchy problem and in the torus with periodic boundary ...

Long-time asymptotic behavior for the Hermitian symmetric space derivative nonlinear Schrödinger equation

open access: yesAdvanced Nonlinear Studies
Resorting to the spectral analysis of the 4 × 4 matrix spectral problem, we construct a 4 × 4 matrix Riemann–Hilbert problem to solve the initial value problem for the Hermitian symmetric space derivative nonlinear Schrödinger equation.

open access: yes, 2010
We discuss state-of-art approaches to modeling of propagation of ultrashort optical pulses in one and three spatial dimensions. We operate with the analytic signal formulation for the electric field rather than using the slowly varying envelope ...

Regularity for critical fractional Choquard equation with singular potential and its applications

open access: yesAdvances in Nonlinear Analysis
We study the following fractional Choquard equation (−Δ)su+u∣x∣θ=(Iα*F(u))f(u),x∈RN,{\left(-\Delta )}^{s}u+\frac{u}{{| x| }^{\theta }}=({I}_{\alpha }* F\left(u))f\left(u),\hspace{1em}x\in {{\mathbb{R}}}^{N}, where N⩾3N\geqslant 3, s∈12,1s\in \left ...

Global solutions to 3D quadratic nonlinear Schrödinger-type equation

open access: yesForum of Mathematics, Sigma
We consider the Cauchy problem to the 3D fractional Schrödinger equation with quadratic interaction of $u\bar u$ type. We prove the global existence of solutions and scattering properties for small initial data.
