ABSTRACT
Let $\tilde{\Omega}\in\mathbb{R}^{N}$ , $N\geq 3$ , be a bounded domain as defined by Flucher, Garroni and Mï¿½ller [6], which has a singular point $\overline{x}\in\partial\tilde{\Omega}$ such that the Robin?s function achieves its infimum at $\overline{x}$ . Considering the elliptic problem $(P_{\varepsilon}): \ -\Delta u = u^{p-\varepsilon},\ u > 0$ in $\tilde{\Omega}$ ; u = 0 on $\partial\tilde{\Omega}$ , with p = ( N + 2)/( N-2), $\varepsilon > 0$ , and $u_{\varepsilon}$ a minimizing solution of $(P_{\varepsilon})$ , $u_{\varepsilon}$ concentrates at $\overline{x}$ as $\varepsilon$ goes to zero.

In this paper, we give an intermediate regularity result on a degenerate elliptic equation with a weight blowing up on the boundary. This kind of equations is encountoured when modelling some phenomena linked to seas or lakes. We give some examples where such regularity is useful.
