摘要：
In this paper we investigate the dynamics of solitons occurring in the nonlinear Schroedinger equation when a parameter h -> 0. We prove that under suitable assumptions, the soliton approximately follows the dynamics of a point particle, namely, the motion of its barycenter q(h)(t) satisfies the equation q(h)(t) + del V (q(h) (t)) = H-h(t) where sup(t is an element of R)vertical bar H-h(t)vertical bar -> 0 as h -> 0.
