Solutions concentrating around the saddle points of the potential for critical Schrödinger equations

  • Jianjun Zhang

We consider the following singularly perturbed nonlinear elliptic problem
$$\begin{aligned} -\varepsilon ^2\Delta u+V(x)u=f(u),\ u\in H^1({\mathbb {R}}^N), \quad N\ge 3, \end{aligned}$$
where f is of critical growth. Using the variational techniques, we construct a solution \(u_\varepsilon \) which concentrates around the saddle points of V as \(\varepsilon \rightarrow 0\).
