Abstract
Let T be a periodic time scale. We use a fixed point theorem due to Krasnosel'skiĭ to show that the nonlinear neutral dynamic equation with delay
xΔ(t) = -α(t)xσ (t) + (Q(t, x(t), x(t - g(t)))))Δ + G(t, x(t), x(t - g(t))), t ∈ T,
has a periodic solution. Under a slightly more stringent inequality we show that the periodic solution is unique using the contraction mapping principle. Also, by the aid of the contraction mapping principle we study the asymptotic stability of the zero solution provided that Q(t, 0, 0) = G(t, 0, 0) = 0.
