文摘
This paper deals with the existence and uniqueness of solutions of the fourth-order periodic boundary value problem where is continuous. Under two-parameter nonresonance conditions described by rectangle and ellipse, some existence and uniqueness results are obtained by using fixed point theorems. These results improve and extend some existing results. MSC: 34B15.
