On the $\text{OUMD}$ property for the column Hilbert space $C$

Abstract

The operator space $\text{OUMD}$ property was introduced by Pisier in the context of vector-valued noncommutative $L_p$-spaces. It is an open problem whether the column Hilbert space has this property. Based on some complex interpolation techniques, we are able to relate this problem to the study of the ${\text{OUMD}}_q$ property for non-commutative $L_p$-spaces.
