Homotopy method for positive solutions of p-Laplace inclusions


In this paper the compression-expansion fixed point theorems are extended to operators which are compositions of two multi-valued nonlinear maps and satisfy compactness conditions of Mönch type with respect to the weak or the strong topology. As an application, the existence of positive solutions for p-Laplace inclusions is studied.
