【 摘 要 】
In this work, we study the oscillatory behavior of even-order neutral delay differential equations$\upsilon ^{n}(l)+b(l)u(\eta (l))=0$ , where$l\geq l_{0}$ ,$n\geq 4$ is an even integer and$\upsilon =u+a ( u\circ \mu ) $ . By deducing a new iterative relationship between the solution and the corresponding function, new oscillation criteria are established that improve those reported in (T. Li, Yu.V. Rogovchenko in Appl. Math. Lett. 61:35–41, 2016).
