New Conditions on Solutions for Periodic Schrödinger Equations with Spectrum Zero

This paper is concerned with the following Schrödinger equation: { − u+ V (x)u = f(x, u), for x ∈ R , u(x) → 0, as |x| → ∞, where the potential V and f are periodic with respect to x and 0 is a boundary point of the spectrum σ(− + V ). By a new technique for showing the boundedness of Cerami sequences, we are able to obtain the existence of nontrivial solutions with mild assumptions on f .

Periodic Solutions for Functional Differential Equations with Periodic Delay Close to Zero

This paper studies the existence of periodic solutions to the delay differential equation ẋ(t) = f(x(t− μτ(t)), ) . The analysis is based on a perturbation method previously used for retarded differential equations with constant delay. By transforming the studied equation into a perturbed non-autonomous ordinary equation and using a bifurcation result and the Poincaré procedure for this last eq...

Symplectic and multi-symplectic methods for coupled nonlinear Schrödinger equations with periodic solutions

We consider for the integration of coupled nonlinear Schrödinger equations with periodic plane wave solutions a splitting method from the class of symplectic integrators and the multi-symplectic six-point scheme which is equivalent to the Preissman scheme. The numerical experiments show that both methods preserve very well the mass, energy and momentum in long-time evolution. The local errors i...

Periodic solutions for systems of coupled nonlinear Schrödinger equations with five and six components.

Systems of coupled nonlinear Schrödinger (CNLS) equations arise in several branches of physics, e.g., optics and plasma physics. Systems with two or three components have been studied intensively. Recently periodic solutions for CNLS systems with four components are derived. The present work extends the search of periodic solutions for CNLS systems to those with five and six components. The Hir...

Rotation Number, Periodic Fučik Spectrum and Multiple Periodic Solutions

In this paper, we will introduce the rotation number for the one-dimensional asymmetric p-Laplacian with a pair of periodic potentials. Two applications of this notion will be given. One is a clear characterization of two unbounded sequences of Fučik curves of the periodic Fučik spectrum of the p-Laplacian with potentials. With the help of the Poincaré–Birkhoff fixed point theorem, the other ap...
