摘要
In this paper, we investigate a class of higher order delay differential equation x(n)(t)+p(t)x(t-t)=0 where is an even positive integer,p()C([to,=()]). We obtain a new oscillation condition for this class.
In this paper, we investigate a class of higher order delay differential equation x^（n）（t）＋（p）x（t-τ）=0 where n is an even positive integer, p∈C（[ t0,＋∞））. We obtain a new oscillation condition for this class.
