Abstract

In this note, we consider the following problem
$$\displaystyle \begin {cases} -\Delta u=(1+g(x))u^{\frac {N+2}{N-2}},\ u>0\text{ in }B,\\ u=0\text{ on }\partial B, \end {cases} $$
where N ≥ 3 and \(B\subset \mathbb {R}^N\) 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.
