Weak convergence of random vectors and distributions in Banach spaces

Let (ξn) be a sequence of random vectors with values in a Banach space X with distributions pξn weakly converging to a given distribution p. We characterize a general form of a distribution of a weak limit of ξ n in Banach space L1(X) of Bochner integrable vectors. We show that the weak convergence of random vectors (ξn) in L1(X) implies that ‖ξn(ω)−ξ(ω)‖ →0 stochastically. Moreover, the conditions ‖ξn(ω)−ξ(ω)‖ →0 stochastically and〈ξn(ω)−ξ(ω), x*〉→0 stochastically for any x*∈X*are
