RT Journal Article T1 A positive fixed point theorem with applications to systems of Hammerstein integral equations A1 Cabada Fernández, Alberto A1 Cid Araújo, José Ángel A1 Infante, Gennaro K1 12 Matemáticas K1 1206.02 Ecuaciones Diferenciales K1 1206.12 Ecuaciones Diferenciales Ordinarias AB We present new criteria on the existence of fixed points that combine some monotonicity assumptions with the classical fixed point index theory. As an illustrative application, we use our theoretical results to prove the existence of positive solutions for systems of nonlinear Hammerstein integral equations. An example is also presented to show the applicability of our results.
