We investigate the existence, multiplicity and nonexistence of positive solutions to nonlinear (singular) elliptic problems involving nonhomogeneous operators and mixed nonlocal boundary conditions based on the behaviors of the nonlinear term near $0$ and $\infty$. In particular, we discuss the exis...

Description
Summary:We investigate the existence, multiplicity and nonexistence of positive solutions to nonlinear (singular) elliptic problems involving nonhomogeneous operators and mixed nonlocal boundary conditions based on the behaviors of the nonlinear term near $0$ and $\infty$. In particular, we discuss the existence of at least three positive solutions to the mixed nonlocal boundary problems, which is new finding even for the problems involving homogeneous operators. The novelty of this study lies in constructing completely continuous operators related to nonlinear elliptic problems involving complicated boundary conditions. We emphasize that only one fixed point theorem is used to obtain the existence and multiplicity results, despite generalizing and extending most of the problems in previous literature.
