Positive stationary solutions for p-Laplacian problems with nonpositive perturbation
Aleksander Cwiszewski, Mateusz Maciejewski
The paper is devoted to the existence of positive solutions of nonlinear elliptic equations with -Laplacian. We provide a general topological degree that detects solutions of th…
