The paper is concerned with the functional differential equation where Ξ» > 0, a(t), b(t), h 1 (t) and h 2 (t) are periodic functions. Applying Leggett-Williams fixed point theorem to the equation, we show the explicit open intervals of Ξ» such that the equation has at least three nonnegative periodi
