In this paper, the existence of nonoscillatory solutions of the first-order neutral delay differential equations with variable coefficients and delays are studied. Some new sufficient conditions are given. In particular, conditions given in this paper are weaker than those known, so the results in t

β¦ Synopsis
The aim of this paper is to study the following first-order nonlinear neutral delay differential equation
By using the Schauder and Krasnoselskii fixed point theorems, we establish the existence of uncountably many bounded nonoscillatory solutions for the above equation. To dwell upon the importance and advantages of our results, seven nontrivial examples are included.

In this paper, some existence theorems of nonoscillatory solutions for nth order nonlinear neutral functional differential equations are obtained. Our results extend some known results in recent years.
For a class of n-th order nonlinear neutral differential equations, sufficient conditions for all nonoscillatory solutions to satisfy lim tβ+β t 1-n x(t) = a are established. For another class of equations, necessary and sufficient conditions for nonoscillatory solutions to satisfy the above conditi
