Boundary singularities of solutions of N-harmonic equations with absorption
Résumé
We study the boundary behaviour of solutions u of $− \Delta_Nu + |u|^{q−1}u = 0$ in a bounded smooth domain $\Omega ⊂ R^N$ subject to the boundary condition u = 0 except at one point, in the range $q >N−1$.We prove that if $q \geq 2N −1$ such an u is identically zero, while, if $N −1
