This paper deals with the existence and uniqueness of solutions of fourth-order periodic boundary value problems. Under two-parameter nonresonance conditions described by rectangle and ellipse, some existence and uniqueness results are obtained by using fixed point theorem. These results improve and extend some existing results.
