Abstract

We consider the elliptic system Δui=ui3+j=1jiq+1βijuiuj2 in R4, i=1,,q+1.-\Delta u_i = u_i^3+\sum\limits_{j=1\atop j\not=i}^{q+1}{ \beta_{ij}}u_i u_j^2\ \hbox{in}\ \mathbb R^4, \ i=1,\dots,q+1. when α:=βij\alpha:=\beta_{ij} and β:=βi(q+1)=β(q+1)j\beta:=\beta_{i(q+1)}=\beta_{(q+1)j} for any i,j=1,,q.i,j=1,\dots,q. If β<0\beta<0 and β|\beta| is small enough we build solutions such that each component u1,,uqu_{1},\dots,u_q blows-up at the vertices of qq polygons placed in different great circles which are linked to each other, and the last component uq+1u_{q+1} looks like the radial positive solution of the single equation.
