Segregated solutions for a critical elliptic system with a small interspecies repulsive force

We consider the elliptic system −Δui = u3 i + q +1 j=1 j=i βijuiu2 j in R4, i = 1,...,q + 1, when α := βij and β := βi(q+1) = β(q+1)j for any i, j = 1, ..., q. If β < 0 and |β| is small enough we build solutions such that each component u1, ..., uq blows-up at the vertices of q polygons placed in...

Descrição
Resumo:We consider the elliptic system −Δui = u3 i + q +1 j=1 j=i βijuiu2 j in R4, i = 1,...,q + 1, when α := βij and β := βi(q+1) = β(q+1)j for any i, j = 1, ..., q. If β < 0 and |β| is small enough we build solutions such that each component u1, ..., uq blows-up at the vertices of q polygons placed in different great circles which are linked to each other, and the last component uq+1 looks like the radial positive solution of the single equation
