## Positive solutions of fourth-order two point boundary value problems.(English)Zbl 1039.34018

Summary: By using the Krasnoselskii fixed-point theorem, we study the existence of one or multiple positive solution of the fourth-order two-point boundary value problem $$y^{(4)}(t)=f(t,y(t),y''(t))$$, $$y(0)=y(1)=y''(0)=y''(1)=0$$. We also give some examples to illustrate our results.
