Abstract: | Let
be a field of Banach space valued random variables, O<r<p≤2 and
a triangular array of real numbers, whereN
d is thed-dimensional lattice (d≥1). Under the minimal condition that
is
integrable, we show that
0 as
. In the above if 0<r<1, the random variables are not needed to be independent. If 1≤r<p≤2, and Banach space valued random variables are independent with mean zero we assume the Banach space is of typep. If 1≤r<p≤2 and Banach space valued random variables are not independent we assume the Banach space isp-smoothable.
