Résumé

We study the equation $- Δ u + h (x) {| u |}^{q - 1} u = 0$ , $q > 1$ , in $ℝ_{+}^{N} = ℝ^{N - 1} \times ℝ_{+}$ where $h \in C (\bar{ℝ_{+}^{N}})$ , $h ⩾ 0$ . Let $(x_{1}, \dots, x_{N})$ be a coordinate system such that $ℝ_{+}^{N} = [x_{N} > 0]$ and denote a point $x \in ℝ^{N}$ by $(x^{'}, x_{N})$ . Assume that $h (x^{'}, x_{N}) > 0$ when $x^{'} \neq 0$ but $h (x^{'}, x_{N}) \to 0$ as $| x^{'} | \to 0$ . For this class of equations we obtain sharp necessary and sufficient conditions in order that singularities on the boundary do not propagate in the interior.
