A counterexample to a nonlinear version of the Krein-Rutman theorem by R. Mahadevan

Abstract

In this short note we present a simple counterexample to a nonlinear version of the Krein-Rutman theorem reported in [Nonlinear Anal. 11 (2007), 3084-3090]. Correct versions of this theorem, and related results for superadditive maps are also presented.
