报告简介：

In this paper we consider a system of three coupled nonlinear Schrodinger equations, which comes from nonlinear optics and Bose-Einstein condensates. We deal with two types: systems with periodic potentials, and systems with trapping potentials. Using the generalized Nehari manifold and delicate energy estimates, we establish the existence of a positive ground state for either type provided that the interacting potentials are suitably small.
