摘要：

In this paper, we consider the second-order nonlinear and the nonlinear neutral functional differential equations (a(t)x'(t))' + f(t, x(g(t))) = 0, t >= t(0) (a(t)(x(t) - p(t)x(t - T))')' + f(t, x(g(t))) = 0, t >= t(0). Using the Banach contraction mapping principle, we obtain the existence of throughout positive solutions for the above equations.
