Conditions $C_p$, $C'_p$, and $C"_p$ for $p$-operator spaces

TL;DR

This paper introduces $p$-operator space analogues of conditions $C$, $C'$, and $C"$, establishing their relationships and characterizations in the context of $L_p$ spaces.

Contribution

It defines conditions $C_p$, $C'_p$, and $C"_p$ for $p$-operator spaces and proves their equivalence under certain conditions, extending classical operator space theory.

Findings

A $p$-operator space on $L_p$ satisfies $C_p$ iff it satisfies $C'_p$ and $C"_p$.

The $p$-operator space injective tensor product is crucial in the analysis.

Extension of classical conditions to the $p$-operator space setting.

Abstract

Conditions $C$, $C'$, and $C"$ were introduced for operator spaces in an attempt to study local reflexivity and exactness of operator spaces (Effros and Ruan, 2000). For example, it is known that an operator space $W$ is locally reflexive if and only if $W$ satisfies condition $C"$ (Effros and Ruan, 2000) and an operator space $V$ is exact if and only if $V$ satisfies condition $C'$ (Effros and Ruan, 2000). It is also known that an operator space $V$ satisfies condition $C$ if and only if it satisfies conditions $C'$ and $C"$ (Effros and Ruan, 2000, and Han, 2007). In this paper, we define $p$-operator space analogues of these definitions, which will be called conditions $C_p$, $C'_p$, and $C"_p$, and show that a $p$-operator space on $L_p$ space satisfies condition $C_p$ if and only if it satisfies both conditions $C'_p$ and $C"_p$. The $p$-operator space injective tensor product of $p$-operator spaces will play a key role.
