Let, for each n ∈ N, (Xi,n) 05i5n be a triangular array of stationary, centered, square integrable and associated real valued random variables satisfying the weakly dependence condition lim N→N0 lim sup n→+∞ n Xn r=N Cov (X0,n, Xr,n) = 0; where N0 is either infinite or the first positive integer N for which the limit of the sum n Pn r=N Cov (X0,n, Xr,n) vanishes as n goes to infinity.
