摘要
本文研究二阶非自治迭代泛函微分方程x''(t)=a(t)x(t)+b(t)x(x(t))的强解的存在性及其性态,给出了过区域{(t,x)|0<x≤t}上任意一点强解存在的条件,得出了过点集{(t,x)|0<x=t}上任意一点存在饱和强解的结论.
The paper studies the behavior and existence of strong solutions to the second order non-autonomous functional differential-iterative equation x'(t)=a(t)x(t)+ b(t)x(x(t)), gives the condition of existence of strong solutions across any point of the region {(t,x)|0 < x ≤ t}, and obtains the conclusion there are maximal strong solutions across any point of the set {(t, x)| 0 < x=t}.
