This paper considers the fourth-order nonlinear differential equations with a deviating argument. Sufficient conditions for the existence and exponential stability of the almost periodic solutions are established, which are new and complement previously known results.
## A new necessary and sufficient condition for the existence of eventually positive solutions is obtained for a class of odd-order neutral differential equations.
The odd order neutral differential equations are considered. New necessary and sufficient conditions, and comparison theorems of existence of eventually positive solutions are obtained. Nonexistence criteria of eventually positive solutions are also established. (~) 2000 Elsevier Science Ltd. All ri
