and Applied Analysis 3 where n ≥ 1 is odd. Grace 27 and Yan 28 obtained several sufficient conditions for the oscillation of solutions of higher-order neutral functional differential equation of the form x t cx t − h Cx t H n qxt − g Qx t G 0, t ≥ t0, 1.8 where q and Q are nonnegative real constants. Clearly, 1.6 is a special case of 1.1 . The purpose of this paper is to study the oscillation b...
