existence of nontrivial solutions of a class of schrödingersystems-意昂体育

摘要: in this talk, we will discuss existence of ground states, existence and multiplicity of bound states, uniqueness of positive solutions of a system of n-coupled time-independent schroedinger equations from nonlinear optics and bose-einstein condensates.this system of schroedinger equations has a very plentiful structure and reveals a lot of new phenomena.
