The Sattinger iteration method for 1-Laplace type problems and its application to concave-convex nonlinearities

Antonio J. Martínez Aparicio, Francescantonio Oliva, Francesco Petitta

In this paper we extend the classical sub-supersolution Sattinger iteration method to -Laplace type boundary value problems of the form \begin{equation*} \begin{cases} \displays…
