早在1951年,H.F ast[6]就引入了统计收敛的定义.之后,出现了许多相关文章(如[4,7-14]等)对统计收敛做了进一步的探索与研究.自上世纪末本世纪初以来,统计收敛作为活跃的领域而得到了深入的研究.例如,统计收敛在数值理论[5],三角级数[15],强可和性[3],局部凸空间[10,13]以及局部紧空间中有界连续函数的理想结构[2]等领域中的讨论.本文通过引入μ-稠密收敛和μ-统计收敛的定义,对于给定一类概率测度U,证明了μ∈U,则序列μ-稠密收敛与统计收敛等价;对μ∈U,序列统计收敛必μ-统计收敛;μ∈U,序列都μ-统计收敛当且仅当序列统计收敛. 相似文献

依概率收敛与依分布收敛的关系 总被引:4,自引:0,他引:4
本探讨了随机变量序列依概率收敛与依分布收敛的关系,并给出了一个依分布收敛能保证依概率收敛的最弱的条件,即:设分布函数列{Fn(x)}弱收敛于连续的分布函数F(x),则存在随机变量序列{ξn}和随机变量ξ,它们分别以{Fn(x)}和F(x)为其对应的分布函数和分面函数,且{ξn}依概率收敛于ξ。 相似文献

Chung and Graham began the systematic study of k‐uniform hypergraph quasirandom properties soon after the foundational results of Thomason and Chung‐Graham‐Wilson on quasirandom graphs. One feature that became apparent in the early work on k‐uniform hypergraph quasirandomness is that properties that are equivalent for graphs are not equivalent for hypergraphs, and thus hypergraphs enjoy a variety of inequivalent quasirandom properties. In the past two decades, there has been an intensive study of these disparate notions of quasirandomness for hypergraphs, and an open problem that has emerged is to determine the relationship between them. Our main result is to determine the poset of implications between these quasirandom properties. This answers a recent question of Chung and continues a project begun by Chung and Graham in their first paper on hypergraph quasirandomness in the early 1990's. © 2013 Wiley Periodicals, Inc.

Consider independent identically distributed random variables (Xi) valued in [0,1]. Let B(n) be the optimal (minimum) number of unit size bins needed to pack n items of size X1, X2,…,Xn. We prove that there exists a numerical constant C such that for t > 0, The constant C does not depend on the distribution of X. 相似文献

Complete and complete moment convergence for weighted sums of widely orthant dependent random variables 总被引:1,自引:0,他引:1
In this paper, we establish a complete convergence result and a complete moment convergence result for weighted sums of widely orthant dependent random variables under mild conditions. As corollaries, the corresponding results for weighted sums of extended negatively orthant dependent random variables are also obtained, which generalize and improve the related known works in the literature. 相似文献

In this paper, the complete convergence and complete moment convergence for arrays of rowwise negatively superadditive dependent (NSD, in short) random variables are investigated. Some sufficient conditions to prove the complete convergence and the complete moment convergence are presented. The results obtained in the paper generalize and improve some corresponding ones for independent random variables and negatively associated random variables. 相似文献
