Compression-expansion fixed point theorem in two norms and applications

Abstract

In this paper we present a two-norms version of Krasnoselskii’s fixed point theorem in cones. The abstract result is then applied to prove the existence of positive \(L_p\)  solutions of Hammerstein integral equations with better integrability properties on the kernels.
