Limiting operations for sequences of quantum random variables and a convergence theorem for quantum martingales [PDF]

open access: green, 2015
We study quantum random variables and generalize several classical limit results to the quantum setting. We prove a quantum analogue of Lebesgue's dominated convergence theorem and use it to prove a quantum martingale convergence theorem.

On Complete Convergence for Weighted Sums of -Mixing Random Variables

open access: greenJournal of Inequalities and Applications, 2010
Some results on complete convergence for weighted sums are presented, where , is a sequence of -mixing random variables and is an array of constants. They generalize the corresponding results for sequence to the case of -mixing sequence.

Complete moment convergence of extended negatively dependent random variables

open access: yesJournal of Inequalities and Applications, 2020
In this paper, some results on the complete moment convergence of extended negatively dependent (END) random variables are established. The results in the paper improve and extend the corresponding ones of Qiu et al. (Acta Math. Appl. Sin. 40(3):436–448,

Complete Convergence for Negatively Dependent Sequences of Random Variables

open access: yesJournal of Inequalities and Applications, 2010
We study the complete convergence for negatively dependent sequences of random variables. As a result, we extend some complete convergence theorems for independent random variables to the case of negatively dependent random variables without necessarily ...

Equivalent Conditions of Complete p-th Moment Convergence for Weighted Sum of ND Random Variables under Sublinear Expectation Space

open access: yesMathematics, 2023
We investigate the complete convergence for weighted sums of sequences of negative dependence (ND) random variables and p-th moment convergence for weighted sums of sequences of ND random variables under sublinear expectation space.

Convergence of weighted sums of independent random variables and an extension to Banach space-valued random variables

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
Let {Xk} be independent random variables with EXk=0 for all k and let {ank:n≥1, k≥1} be an array of real numbers. In this paper the almost sure convergence of Sn=∑k=1nankXk, n=1,2,…, to a constant is studied under various conditions on the weights {ank ...

Complete convergence and complete moment convergence for negatively associated sequences of random variables

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we study the complete convergence and complete moment convergence for negatively associated sequences of random variables with E X = 0 $\mathbb{E}X=0$ , E exp ( ln α | X | ) < ∞ $\mathbb{E}\exp(\ln^{\alpha}|X| ) 1 $\alpha>1$ . As a result,
