摘要: 利用Rosenthal不等式, 讨论随机变量序列加权和的几乎处处收敛性. 将经典概率空间中END序列加权和的几乎处处收敛性推广到次线性期望下m-END随机变量序列加权和的几乎处处收敛性.

关键词: 次线性期望, m-END随机变量序列, 加权和, 几乎处处收敛

Abstract: By using Rosenthal’s inequality, we discussed almost sure convergence of weighted sums for m-END (m-extended negatively dependent) random variable sequence. Almost sure convergence of weighted sums for END sequence in the classical probability space was extended to the almost sure convergence of weighted sums for m-END random variable sequence under the sub-linear expectations.

Key words: sub-linear expectation, m-extended negatively dependent random variable sequence, weighted sum, almost sure convergence
