摘要：

研究了一类中立型部分带有分布时滞且具有正负系数的分数阶微分方程，利用 Banach 压缩映像原理，通过克服算子构造和不等式放缩技巧，得到了方程有界的非振动解存在的充分条件，将其系数的适用范围拓展成不等于 1 和 $-1$ 的实数，并通过算例验证了相关结果。

关键词: 分数阶, Liouville 导数, 正负系数, 分布时滞, 非振动解

Abstract:

A class of neutral fractional differential equations with  distributed delays and positive and negative coefficients are investigated. Using the Banach contraction mapping principle, by overcoming the operator construction and inequality scaling techniques, the sufficient conditions for the existence of bounded nonoscillatory solutions of the equations is obtained. Especially, the applicable range of these coefficients is extended to real numbers that are not equal to 1 and $-1$, the relevant results are verified by some examples.

Key words: fractional differential equation, Liouville derivative, positive and negative coefficients, distributed delays, nonoscillatory solutions
