摘要
通过研究上可加的r阶矩结构的随机序列和的几乎必然收敛性、收敛速度,给出了2个重要定理的证明,得出的随机序列和的收敛速度在数量级上已达到最优,并给出了定理的相关应用.
In this paper, we mainly study almost sure convergence for the sums of random sequence under rth moment function of superadditive properties and convergence rate, and prove three important theorems. We obtain the best convergence rate for the sums of random sequence on the order of magnitude. The application is known, we obtain a new theorem.
