本文研究抽象空间B中无限时滞随机泛函微分方程解的存在唯一性,在弱化的线性增长条件和一致Lipschitz条件下,得到无限时滞随机泛函微分方程在区间[0,∞)上存在唯一解,进而,得到近似解与精确解之间的误差估计。
The existence and uniqueness of the solutions to stochastic functional differential equations with infinite delay at phase space B is considered in this paper.Under the weaken linear growth condition and uniform Lipschitz condition,the system has a unique solution on the interval [0,∞).Then the moment estimate for the error between approximate solution and accurate solution is given.
