New Results on Oscillation of even Order Neutral Differential Equations with Deviating Arguments ()
Abstract
In this paper, we point out some small mistakes in [6] and revise them, we obtain some new oscillation results for certain even order neutral differential equations with deviating arguments. Our results extend and improve many known oscillation criteria because the article just generalizes Meng and Xu’s results.
