A priori estimates and existence for quasilinear elliptic equations with nonlinear Neumann boundary conditions

Zhe Hu, Li Wang, Peihao Zhao

Abstract:
This article concerns the existence of positive solutions for a nonlinear Neumann problem involving the m-Laplacian. The equation does not have a variational structure. We use a blow-up argument and a Liouville-type theorem to obtain a priori estimates and obtain the existence of positive solutions by the Krasnoselskii fixed point theorem.
