This is an announcement for the paper "The norm of sums of independent
non-commutative random variables in $L_p(\ell_1)$" by Marius Junge
and Javier Parcet.
Abstract: We investigate the norm of sums of independent vector-valued
random variables in non-commutative Lp spaces. This allows us to obtain
a uniform family of complete embeddings of the Schatten class Sq^n
in Sp(lq^m) with optimal order m=n^2. Using these embeddings we show
the surprising fact that the sharp type (cotype) index in the sense of
operator spaces for Lp[0,1] is min(p,p') (max(p,p')). Similar techniques
are used to show that the operator space notions of B-convexity and
K-convexity are equivalent.
