Abstract
Let α, s and t be real numbers satisfying 0<α1. We first establish the equivalence between partial differential system and weighted integral system{u(x)=â«Rnvq(y)|xây|nâα|y|sdy,v(x)=â«Rnup(y)|xây|nâα|y|tdy. Then, in the critical case of nâsq+1+nâtp+1=nâα, we show that every pair of positive solutions (u(x),v(x)) is radially symmetric about the origin. While in the subcritical case, we prove the nonexistence of positive solutions.
