,where Pn,0(x) denotes the limit of Pn,r (x) as r → 0 + and where qi > 0, 1 ≤ i ≤ n, are positive real numbers with n=1 qi = 1 and x = (x1 ,x 2 ,...,x n). In this note, we let q = min qi and always assume n ≥ 2 and 0 ≤ x1 <x 2 < ··· <x n. We define An(x) = Pn,1(x), Gn(x) = Pn,0(x), and Hn(x) = Pn,−1(x) and we will write Pn,r for Pn,r (x), An for An(x), and similarly for other means when there is no risk of confusion. For mutually distinct numbers r , s, and t and any real number α and β ,w e define
