In this note, we consider the following problem− Δ u=(1+ g (x)) u N+ 2 N− 2, u> 0 in B, u= 0 on∂ B, where N≥ 3 and B⊂ ℝ N is the unit ball centered at the origin and g (x) is a radial Hölder continuous function such that g (0)= 0. We prove the existence and nonexistence of radial solutions by the variational method with the concentration compactness analysis and the Pohozaev identity.
