Existence and non-existence results for quasilinear elliptic exterior problems with nonlinear boundary conditions. (English) Zbl 1147.35038
Summary: Existence and non-existence results are established for quasilinear elliptic problems with nonlinear boundary conditions and lack of compactness. The proofs combine variational methods with the geometrical feature, due to the competition between the different growths of the nonlinearities.
