摘要 随机变量的一致可积概念自从提出以来,一直是概率极限理论研究中的热点问题,并且一些研究者已经给出了一些经典的结论。在本文中,作者提出一种改进的Cesàroα一致可积的条件,该条件比文献[3]和[4]中所提起到的可积条件要弱,并且在该可积条件下给出了随机变量和的完全收敛定理,与此同时还给出了一个两两LCND随机变量序列和的完全收敛定理。 The notion of the uniform integrability plays the central role in the areaof limit Theor-ems in Probability Theory.Some researchers have given some classic conclusions In this paper,a new set of properties called residually Cesàro integrabiity are gived,which condition are weaker that the condition of integrabiity in[3] and [4].Under the condition of residually Cesàro integrabiity,we establish complete convergence for random sums of nonnegative random variables and pairwise LCND random variables.
