We study completely continuous maps in ordered Banach spaces having an invariant cone. We give conditions on minorants and majorants which yield the existence of at least one non-zero fixed point.

In this article we study the existence of radially symmetric solutions to a superlinear Dirichlet problem in annular domain in $\mathbb{R}^N$. Using fairly straightforward tools of the theory of ordinary differential equations, we show that if k i
