In this paper we investigate the oscillation and asymptotic behavior of solutions to the n-th order neutral nonlinear differential equations of the form \begin{equation*} \left[ x(t) +g\left( t, x(\tau( t))\right) \right] ^{(n) }+f( t,x(\sigma(t))) =

In this paper, we consider the second-order nonlinear and the nonlinear neutral functional differential equations $$displaylines{ (a(t)x'(t))'+f(t,x(g(t)))=0,quad tgeq t_0cr (a(t)(x(t)-p(t)x(t-au))')'+f(t,x(g(t)))=0,quad tgeq t_0,. }$$ Using the Bana
