We use the nonlinear alternative and topological transversality to prove an existence theorem for the solutions of the functional differential equation αΊ‹(t) = F (t, x t ), where x t (ΞΈ ) = x(t + ΞΈ ) for all ΞΈ ∈ [-r, 0] and F : [0, A] Γ— X 2 β†’ X , X is a Banach space and X 2 is the Banach space of con
