| Abstract | |
We provide sufficient conditions for the existence of periodic solutions of the fourth-order differential equation u '''' + qu '' - u = epsilon F (u, u', u '', u ''') , where q and e are real parameters, E is small and F is a nonlinear function. (C) 2011 Elsevier Inc. All rights reserved. (AU) | |
