Positive solutions of a third order nonlocal boundary value problem. (English) Zbl 1153.34014

Guo-Krasnosel’skii fixed point theorem is used to provide sufficient conditions so that a third order nonlinear differential equation together with some boundary conditions have positive solutions. Some results of negative nature are also proved. The paper concludes with an illustrative example.
