In this paper,we study the following N-coupled nonlinear Schrodinger system■,wheren≤3,N≥3,uj>0,βi,j=βj,i>0 are constants andβj,j=μj,j=1,...,N.There have
In this paper we introduce a new deformation argument,in which C0-group action and a new ty pe of Palais Smale condition PSP play important roles.This type of d
