Boundary singularities of solutions of N-harmonic equations with absorption

Rouba Borghol, Laurent Veron

We study the boundary behaviour of solutions $u$ of $- Δ_{N} u + ∣ u ∣^{q - 1} u = 0$ in a bounded smooth domain $Ω \subset R^{N}$ subject to the boundary condition $u = 0$ except at one…

Boundary Harnack inequality and a priori estimates of singular solutions of quasilinear elliptic equations

Marie-Francoise Bidaut-Veron, Rouba Borghol, Laurent Veron

We extend some classical results dealing with boundary Harnack inequatilities to a class of quasilinear elliptic equations and derive some new estimates for solutions of such equat…

Boundary singularities of N -harmonic functions

Rouba Borghol, Laurent Veron

We construct N-harmonic functions in a domain with one isolated singularity on the boundary of the domain. By using solutions of the spherical p-harmonic spectral problem, we give…
