In this work, we address an interesting problem in studying the oscillatory behavior of solutions of fourth-order neutral delay differential equations with a non-canonical operator. We obtained new criteria that improve upon previous results in the literature, concerning more than one aspect. Some examples are presented to illustrate the importance of the new results.

测试非规范中性时滞微分方程振动的更有效结果

在这项工作中，我们解决了一个有趣的问题，即使用非规范算子研究四阶中立型时滞微分方程解的振动行为。我们获得了新的标准，这些标准改进了文献中涉及多个方面的先前结果。给出了一些例子来说明新结果的重要性。
