Convergence properties for weighted sums of weakly dependent random vectors in Hilbert spaces

In this paper, some results on the complete moment convergence, complete convergence, complete integral convergence, and strong law of large numbers for weighted sums of weakly dependent random vectors in Hilbert spaces are established. The results obtained in this paper improve and extend the corresponding ones of Sung [Complete convergence for weighted sums of -mixing random variables, Discrete Dyn. Nat. Soc. 2010 (2010), Article ID 630608, 13 pages], Huan [Baum-Katz type theorems for coordinatewise negatively associated random vectors in Hilbert spaces, Acta Math. Hungar. 144(1) (2014), pp. 132-149], Huan [On complete convergence for sequences of random vectors in Hilbert spaces, Acta Math. Hungar. 147(1) (2015), pp. 205-219], and Ko [The complete moment convergence for CNA random vectors in Hilbert spaces, J. Inequal. Appl. 2017 (2017), Article ID 290, 11 pages].
