Some Oscillation Results for Even-Order Differential Equations with Neutral Term

The objective of this work is to study some new oscillation criteria for even-order differential equation with neutral term rxzn-1x gamma & PRIME;+qxy gamma zeta x=0. By using the Riccati substitution and comparison technique, several new oscillation criteria are obtained for the studied equation. Our results generalize and improve some known results in the literature. We offer some examples to illustrate the feasibility of our conditions.
