Abstract
We shall firstly study the existence of one positive solution of a model problem for one equation via the classical Krasnosel'ski\u\i{} fixed-point theorem. Secondly we investigate how to handle this problem via the fixed point index theory for compact maps. Thirdly we illustrate how this approach can be tailored in order to deal with non-trivial solutions for systems of ODEs subject to local BCs. The case of nonlocal and nonlinear BCs will also be investigated. Finally we present some applications to the existence of radial solutions of some systems of elliptic PDEs.
