Oscillatory behavior of $n$-th order nonlinear delay differential equations with a nonpositive neutral term

Abstract

We study the oscillation problem for solutions of a class of $n$-th order nonlinear delay differential equations with nonpositive neutral terms. The obtained results improve and correlate many of the known oscillation criteria in the literature for neutral and non-neutral equations.

Keywords

• Oscillation,neutral term,second order differential equation
