Oscillatory Behavior of Higher-Order Delay Differential Equations

O. Bazighifan

This paper is concerned with asymptotic and oscillatory properties of the nonlinear higher-order differential equation with delay argument. Some examples are given to illustrate our main result.

An Oscillation Criterion in Delay Differential Equations

George E. Chatzarakis

Consider the first order linear delay differential equation x0(t) + p(t)x(τ(t)) = 0, t ≥ t0, where p is a continuous function of nonnegative real numbers and the argument τ(t) is not necessarily monotone. Based on an iterative technique, a new oscillation criterion is established when the well-known ...
