一类偶阶中立型分布时滞不等式最终正解的不存在性

摘要

研究一类具有偏差变元的偶数阶中立型时滞不等式，运用完全平方的技术及Schwarz不等式，得到了该类不等式几个新的最终正解不存在准则，推广了已有的一些结果。%A class of even order neutral functional differential inequalities with distributed deviating ar-guments was considered, and by adopting integrality square technical and Schwarz inequality,several new re-sults related to the nonexistence criteria for eventually positive solutions of certain even order neutral were de-veloped . The works generalize various existing results.
