Asymptotic stability of soliton for discrete nonlinear Schr\"odinger equation on one-dimensional lattice

  title={Asymptotic stability of soliton for discrete nonlinear Schr\"odinger equation on one-dimensional lattice},
  author={Masaya Maeda and Masafumi Yoneda},
In this paper we give a simple and short proof of asymptotic stability of soliton for discrete nonlinear Schrödinger equation near anti-continuous limit. Our novel insight is that the analysis of linearized operator, usually non-symmetric, can be reduced to a study of simple self-adjoint operator almost like the free discrete Laplacian restricted on odd functions. 



Revisiting asymptotic stability of solitons of nonlinear Schrödinger equations via refined profile method

In this paper, we give an alternative proof for the asymptotic stability of solitons for nonlinear Schrödinger equations with internal modes. The novel idea is to use “refined profiles” developed by

Asymptotic behaviour of small solutions for the discrete nonlinear Schrödinger and Klein–Gordon equations

We show decay estimates for the propagator of the discrete Schrödinger and Klein–Gordon equations in the form . This implies a corresponding (restricted) set of Strichartz estimates. Applications of

Asymptotic Stability of Small Bound States in the Discrete Nonlinear Schrödinger Equation

Asymptotic stability of small bound states in one dimension is proved in the frame- work of a discrete nonlinear Schrodinger equation with septic and higher power-law nonlinearities and an external

Stabilization of small solutions of discrete NLS with potential having two eigenvalues

ABSTRACT We study the long-time behavior of small (in ) solutions of discrete nonlinear Schrödinger equations with potential. In particular, we are interested in the case that the corresponding

A survey on asymptotic stability of ground states of nonlinear Schrödinger equations II

We give short survey on the question of asymptotic stability of ground states of nonlinear Schrodinger equations, focusing primarily on the so called nonlinear Fermi Golden Rule.

Asymptotic Stability of Breathers in Some Hamiltonian Networks of Weakly Coupled Oscillators

We consider a Hamiltonian chain of weakly coupled anharmonic oscillators. It is well known that if the coupling is weak enough then the system admits families of periodic solutions exponentially

Multichannel nonlinear scattering for nonintegrable equations

We consider a class of nonlinear Schrödinger equations (conservative and dispersive systems) with localized and dispersive solutions. We obtain a class of initial conditions, for which the asymptotic
