Özet

In this work, oscillatory and asymptotic behaviours of all Solutions of higher-order neutral differential equations are compared with first-order delay differential equations, depending oil two different ranges of the coefficient associated with the neutral part. Some simple examples are given to compare or results With the existing results In the literature and to illustrate the significance and applicability of our new results. Our results generalise, improve and correct some of the existing results in the literature.
