The approach relies an extension of Krasnoselskii’s fixed point theorem in a cone. Some examples are given to illustrate our results.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Green's functionsFourth-order boundary value problemIntegral boundary conditions, positive solutionsExtension of Krasnoselskii's fixed point theorem in a cone120219 Ecuaciones diferenciales ordinariasjournal article10.14232/ejqtde.2020.1.70open access
