Abstract

In this paper, the existence results of positive solutions are obtained for a fourth-order boundary value problem with parameters, then by using the fixed point theorem in cone and the system of integral equation, an existence theorem is established.

Keywords and phrases: positive solution, cone, fixed point index.
