Abstract
In this paper we study the existence of periodic solutions with prescribed wavelength for two classes of nonlocal fourth-order nonautonomous differential equations. Existence of nontrivial solutions for the first equation is proved using Clark’s theorem. Existence of nontrivial solutions for the second equation is proved using the symmetric mountain-pass theorem.
