Abstract
We establish the existence of periodic solution of a class of non-autonomous second-order systems, over(x, ̈) + μ x + V (t, x) = 0, where V (t, x) = (v1 (t, x), ..., vn (t, x)), if lim| x | → ∞ frac(vi (t, x), | x |) = 0, i = 1, ..., n, uniformly in t and V is bounded below or above for appropriate ranges of μ.
