Fourier mode dynamics for the nonlinear Schroedinger equation in one-dimensional bounded domains

open access: yes, 2011
We analyze the 1D focusing nonlinear Schr\"{o}dinger equation in a finite interval with homogeneous Dirichlet or Neumann boundary conditions. There are two main dynamics, the collapse which is very fast and a slow cascade of Fourier modes.

Variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition

open access: yesLe Matematiche, 2010
The aim of this paper is the study of variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition. Sufficient conditions for the existence of a whole sequence of solutions which is either unbounded or converges to zero are ...

Fractional diffusion with Neumann boundary conditions: The logistic equation

open access: yesDiscrete & Continuous Dynamical Systems - B, 2013
Motivated by experimental studies on the anomalous diffusion of biological populations, we introduce a nonlocal differential operator which can be interpreted as the spectral square root of the Laplacian in bounded domains with Neumann homogeneous boundary conditions.

Dynamics of a diffusive delayed competition and cooperation system

open access: yesOpen Mathematics, 2020
In this manuscript, we first consider the diffusive competition and cooperation system subject to Neumann boundary conditions without delay terms and get the conclusion that the unique positive constant equilibrium is locally asymptotically stable. Then,

A singular nonlinear boundary value problem with Neumann conditions [PDF]

open access: yesOpuscula Mathematica, 2005
We study the existence of solutions for the equations \(x^{\prime\prime}\pm g(t,x)=h(t)\), \(t\in (0,1)\) with Neumann boundary conditions, where \(g:[0,1] \times (0,+\infty) \to [0,+\infty)\) and \(h:[0,1] \to \mathbb{R}\) are continuous and \(g(t,\cdot)

Boundary stabilization and control of wave equations by means of a general multiplier method

open access: yes, 2009
We describe a general multiplier method to obtain boundary stabilization of the wave equation by means of a (linear or quasi-linear) Neumann feedback. This also enables us to get Dirichlet boundary control of the wave equation.
