Abstract
We verify the existence of radial positive solutions for the semilinear equation (Formula presented.) where N ≥ 3, p is close to p* ≔ (N+ 2)/(N − 2), and V is a radial smooth potential. If q is supercritical, namely q > p*, we prove that this problem has a radial solution behaving like a superposition of bubbles blowingup at the origin with different rates of concentration, provided V(0) < 0. On the other hand, if N/(N − 2) < q < p*, we prove that this problem has a radial solution behaving like a superposition of flat bubbles with different rates of concentration, provided lim _{r→∞}V(r) < 0.
