摘要 运用黎卡提变换研究了一类非线性时滞微分方程 ,得到了它的单调解存在性的充要条件 ,并应用这些条件获得了这类方程单调解存在性的几个判据与比较定理 . By means of a Riccati-type transformation,a class of nonlinear delay differential equation is investigated and necessary and sufficient conditions are obtained for the existence of monotone solution of a nonlinear delay differential equation.As application,several existence criteria and comparison theorems are derived
