Abstract

In this work, the authors consider the boundary value problem {(y + a (t) y = g (t) f (y), 0 ≤ t ≤ 2 π,; y (0) = y (2 π), y (0) = y (2 π),) and establish the existence of nonnegative solutions in the case where the associated Green's function may have zeros. The results are illustrated with an example.
