We deal with the existence of positive radial solutions concentrating on spheres for the following class of elliptic system (S) [수식], where ε is a small positive parameter; V1, V2 ∈ C0(RN, [0,1)) and K 2 C0(RN, (0,∞)) are radially symmetric potentials; Q is a (p + 1)- homogeneous function and p is subcritical, that is, 1 < p < 2∗ −1, where 2∗ = 2N/(N − 2) is the critical Sobolev exponent for N ≥ 3.
