摘要：

We study the oscillation of first-order delay equations using a method that parallels the use of Riccati equations in the study of the oscillation of second-order ordinary differential equations without delay. We give an alternative proof of a comparison theorem first established by Kwong and Patula, obtain some asymptotic behaviors of nonoscillatory solutions, prove a new criterion that falls within a gap left open by established results, and confirm a conjecture raised by Hunt and Yorke. © 1991.
