| Abstract: | By means of Laplace transformation, it's discussed in this paper to show the relation between the nonoscillatory solutions for a kind of higher order neutral differential equation and the distribution for real-roots of their characteristic equations. At the same time,some necessary and sufficient conditions are given that describe the existence of some kinds of nonoscillatory solutions for the above higher order neutral differential equation. |
| Keywords: | neutral differential equation nonoscillation solution characteristic equation |
