Abstract.  We study in this article, the existence and uniqueness of a solution for nonlinear elliptic problemswith non-local boundary conditions. In order to get the unique solution, we study first an auxiliary problem, for which, we deduce useful a priori estimates. The study of the auxiliary problem give us equivalence between this kind of problem and nonlinear problem with very large diffusion around the boundary.
Keywords: Non-local boundary conditions, Leray-Lions type operator, Operator of type M, Standard monotonicity arguments.
