报告摘要  Abstract

In this talk, we will consider some types of Hamiltonian DNLS equations with periodic boundary conditions.  When its initial value of the solution is small, we will research the behavior of the corresponding solutions during a long time interval.  We will change these problem into consider the solution around origin point to an infinite dimension nearly integrable Hamiltonian systems. The main methods are Birkhoff normal theory and energy estimate.
