摘要：
Let $1\le p<2$ and $0<\alpha , \beta <\infty $ with $1/p=1/\alpha +1/\beta $. Let $\{X_{n}, n\ge 1\}$ be a sequence of random variables satisfying a generalized Rosenthal type inequality and stochastically dominated by a random variable X with $E|X|^{\beta }< \infty $. Let $\{a_{nk}, 1\le k\le n, n\ge 1\}$ be an array of constants satisfying $\sum_{k=1}^{n} |a_{nk}|^{\alpha }=O(n)$. Marcinkiewicz–Zygmund type strong laws for weighted sums of the random variables are established. Our results generalize or improve the corresponding ones of Wu (J. Inequal. Appl. 2010:383805, 2010), Huang et al. (J. Math. Inequal. 8:465–473, 2014), and Wu et al. (Test 27:379–406, 2018).

摘要：
In this paper, the complete convergence theorems for Sung’s type weighted sums of END random variables and PNQD random variables with general moment conditions are obtained. The theorems extend the related known works in the literature.

摘要：
In this paper, the complete convergence for the weighted sums of independent and identically distributed random variables in Stout [9] is improved and extended under NOD setup. The more optimal moment condition is given. The main results also hold for END sequence.
