### Abstract

^{n}with smooth boundary ∂Ω. We consider the equation ∆

*u + u n−k+2 n−k−2−ε*= 0 in Ω, under zero Dirichlet boundary condition, where ε is a small positive parameter. We assume that there is a

*k*-dimensional closed, embedded minimal sub-manifold

*K*of ∂Ω, which is non-degenerate, and along which a certain weighted average of sectional curvatures of ∂Ω is negative. Under these assumptions, we prove existence of a sequence

*ε = εj*and a solution

*u*which concentrate along

_{ε}*K*, as

*ε*→ 0+, in the sense that |∇

*u*|2 * S

_{ε}*n−k 2 n−k δK*as

*ε → 0*where δK stands for the Dirac measure supported on

*K*and

*Sn−k*is an explicit positive constant. This result generalizes the one obtained in [17], where the case

*k*= 1 is considered.

N2 - Let Ω be an open bounded domain in Rn with smooth boundary ∂Ω. We consider the equation ∆u + u n−k+2 n−k−2−ε = 0 in Ω, under zero Dirichlet boundary condition, where ε is a small positive parameter. We assume that there is a k-dimensional closed, embedded minimal sub-manifold K of ∂Ω, which is non-degenerate, and along which a certain weighted average of sectional curvatures of ∂Ω is negative. Under these assumptions, we prove existence of a sequence ε = εj and a solution uε which concentrate along K, as ε → 0+, in the sense that |∇uε|2 * S n−k 2 n−k δK as ε → 0 where δK stands for the Dirac measure supported on K and Sn−k is an explicit positive constant. This result generalizes the one obtained in [17], where the case k = 1 is considered.
