Convergence of weighted sums of random variables and uniform integrability concerning the weights
(Universitat de Barcelona, 1994)
Let {ank}, n, k ∈ N be an array of real constants, and let {Xn} be a sequence of random variables. The concept of {ank}-uniform integrability of {Xn} is defined and two characterizations of this concept are established. ...
