Resumen en inglés In this paper we study the regularity of the solutions to the problem ∆pu = |u| p−2u in the bounded smooth domain Ω ⊂ RN , with |∇u| p−2 ∂u ∂ν = λV (x)|u| p−2u+h as a nonlinear boundary condition, where ∂Ω is C2,β with β ∈]0, 1[, and V is a weight in Ls (∂Ω) and h ∈ Ls (∂Ω) for some s ≥ 1. We prove that all solutions are in L∞(∂Ω) T L∞(Ω), and using the D.Debenedetto’s theorem of regularity in [1] we conclude that those solutions are in C1,α Ω for some α ∈[0, 1]
