## Abstract

Let $Ω$ be a bounded domain in $R_{n}$ with smooth boundary $∂Ω$. We consider the equation $d_{2}Δu−u+u_{n−k−2n−k+2}=0inΩ$ , under zero Neumann boundary conditions, where $Ω$ is open, smooth and bounded and $d$ is a small positive parameter. We assume that there is a $k$-dimensional closed, embedded minimal submanifold $K$ of $∂Ω$, which is non-degenerate, and certain weighted average of sectional curvatures of $∂Ω$ is positive along $K$. Then we prove the existence of a sequence $d=d_{j}→0$ and a positive solution $u_{d}$ such that

in the sense of measures, where $δ_{K}$ stands for the Dirac measure supported on $K$ and $S$ is a positive constant.
