Abstract
In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of $T$-periodic solutions for the first order neutral functional differential equation with a deviating argument of the form \[ (x(t) + Bx(t-\delta))' = g_1(t,x(t)) + g_2(t, x(t-\tau(t))) + p(t). \]
