Existence of homoclinic solutions for a fourth order differential equation with a parameter

Tiexiang Li; Juntao Sun; Tsung-fang Wu

In this paper, we study the existence of homoclinic solutions for a class of fourth order differential equations. By using variational methods, the existence and the non-existence of nontrivial homoclinic solutions are obtained, depending on a parameter.
