Well-posedness of a higher-order Schrödinger–Poisson–Slater system

open access: yesBoundary Value Problems, 2018
In this paper, we show the global well-posedness of a higher-order nonlinear Schrödinger equation. Specifically, we consider a system of infinitely many coupled higher-order Schrödinger–Poisson–Slater equations with a self-consistent Coulomb potential ...

Meromorphic solutions of nonlinear ordinary differential equations [PDF]

open access: yes, 2010
Exact solutions of some popular nonlinear ordinary differential equations are analyzed taking their Laurent series into account. Using the Laurent series for solutions of nonlinear ordinary differential equations we discuss the nature of many methods for

On Galilean invariance and nonlinearity in electrodynamics and quantum mechanics [PDF]

open access: yes, 2000
Recent experimental results on slow light heighten interest in nonlinear Maxwell theories. We obtain Galilei covariant equations for electromagnetism by allowing special nonlinearities in the constitutive equations only, keeping Maxwell's equations ...

Global existence and blow-up for a class of nonlocal nonlinear Cauchy problems arising in elasticity [PDF]

open access: yes, 2009
We study the initial-value problem for a general class of nonlinear nonlocal wave equations arising in one-dimensional nonlocal elasticity. The model involves a convolution integral operator with a general kernel function whose Fourier transform is ...

Thresholds for global existence and blow-up in a general class of doubly dispersive nonlocal wave equations [PDF]

open access: yes, 2013
In this article we study global existence and blow-up of solutions for a general class of nonlocal nonlinear wave equations with power-type nonlinearities, $u_{tt}-Lu_{xx}=B(- |u|^{p-1}u)_{xx}, ~(p>1)$, where the nonlocality enters through two pseudo ...
