摘要：
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. (C) 2000 Elsevier Science Ltd. All rights reserved.
