New oscillation criteria for the second‐order Emden–Fowler delay differential equation with a sublinear neutral term are presented. An essential feature of our results is that oscillation of the studied equation is ensured via only one condition. Furthermore, as opposed to the results by Agarwal et al. (Ann. Mat. Pura Appl. (4) 193 (2014), no. 6, 1861–1875), Li and Rogovchenko (Math. Nachr. 288 (2015), no. 10, 1150–1162; Monatsh. Math. 184 (2017), no. 3, 489–500), and Xu (Monatsh. Math. 150 (2007), no. 2, 157–171), new criteria can be applied to Emden–Fowler delay differential equations with noncanonical operators and a sublinear neutral term. Our results essentially improve, extend, and simplify some known ones reported in the literature. The results are illustrated with examples.

具有亚线性中性项的二阶Emden-Fowler时滞微分方程的振动准则

提出了具有亚线性中性项的二阶Emden-Fowler时滞微分方程的新振动准则。我们的结果的基本特征是仅通过一个条件就可以确保研究方程的振动。此外,与Agarwal等人的结果相反。(安垫普拉申请(4)。193(2014),6号,1861年至1875年),Li和Rogovchenko(数学胆碱受体。288(2015),无10,1150至1162年; Monatsh数学。184(2017),第3期,489-500),和许(Monatsh。数学。150(2007),没有。2,157–171),新准则可以应用到具有非规范算子和亚线性中性项的Emden-Fowler时滞微分方程。我们的结果实质上改善,扩展和简化了文献中报道的一些已知结果。实例说明了结果。
