偶阶中立型多时滞泛函微分不等式最终正解的不存在性

The Nonexistence for Eventually Positive Solutions of Even Order Neutral Functional Differential Inequality with Multiple Delays

利用广义黎卡提变换和积分平均技巧,研究了一类非线性的偶数阶中立型多时滞泛函微分不等式,得到了该类不等式几个新的最终正解不存在准则,所得结果推广了最近文献的相关结果,具有重要意义.

Using a generalized Riccati transformation and integral averaging technique,we develop sev-eral new results related to the nonexistence criteria for eventually positive solutions of certain even order neutral functional differential inequalities with multiple delays.The results extend and improve the ones in recent liter-ature,and have important significance.
