【摘要】 本文研究了一类非自治迭代泛函微分方程ｘ′（ｔ）＝（ｘ２（ｔ）－ｔ２）ｆ（ｘ（ｘ（ｔ）））（其中ｆ∈Ｃ（Ｒ，Ｒ），单调递增，ｚｆ（ｚ）＞０，ｚ≠０）满足初始条件ｘ（σ）＝σ＞０，或满足初始条件ｘ（σ）＝－σ＜０的解的性态、解的存在性及延拓问题．更多还原

【Abstract】 This paper studies the behavior of solutions of nonautonomous functional differential iterative equations x′(t)=(x 2(t)-t 2)f(x(x(t))), where f∈C(R,R),f is increasing and zf(z)>0, if z≠0 . When the equation satisfies initial condition x(σ)=σ>0 or x(σ)=-σ<0 ,the existence and continuation of solutions are given.更多还原
