摘要
We investigate the solvability of a fully fourth-order periodic boundary value problem of the form x((4)) = f (t, x, x', x '', x'''), x((i)) (0) = x((i))(T), i = 0, 1, 2, 3, where f : [0, T] x R-4 --> R satisfies Caratheodory conditions. By using the coincidence degree theory, the existence of nontrivial solutions is obtained. Meanwhile, as applications, some examples are given to illustrate our results.
