Abstract

Given a linear Sturm-Liouville operator Lu=(pu′)′ — qu and a nonlinear Nemytskij operator F(u)=f(,u,u′), we prove existence theorems for the equation Lu=F(u) by means of sharp fixed point theorems for the (usually noncompact) operator A=L−1F. By a "sharp fixed point theorem" we mean the problem of finding or estimating the highest admissible growth and non-compactness of A still guaranteeing the existence of fixed points.
