New oscillation criteria for first order nonlinear delay differential equations

Xianhua Tang; Jianhua Shen — 2000

Colloquium Mathematicae

New oscillation criteria are obtained for all solutions of a class of first order nonlinear delay differential equations. Our results extend and improve the results recently obtained by Li and Kuang [7]. Some examples are given to demonstrate the advantage of our results over those in [7].
