Combined effects and degenerate phenomena in nonlinear stationary problems
Abstract
In this survey paper we are concerned with several nonlinear stationary problems involving nonhomogeneous differential operators. We report on some recent qualitative results related with various nonlinear problems in Orlicz-Sobolev spaces. Our analysis combines spectral analysis techniques with variational methods.
