摘要 利用Ito公式、BDG不等式及Holder不等式,在Ch空间中得到无限时滞随机泛函微分方程解的p阶矩估计、样本Liapunov指数估计,并进一步得到p阶矩的连续性等结论. By using of Ito formula,BDG inequality and Holder inequality,the pth moment estimate and the sample Liapunov exponential estimate of the solution for stochastic functional differential equations with infinite delay are discussed in Ch space.Further,the continuity for the pth moment is obtained.
