Nonlinear four-point problem: Non-resonance with respect to the Fučík spectrum Original Research Article

We study the solvability of a nonlinear four-point boundary value problem. We focus on the non-resonance case with respect to the Fučík spectrum and we show the difference between regions of type I and regions of type II. Qualitatively different patterns of regions of both types can be obtained using various settings of problem parameters.
