从$C^*$ -代数到von Neumann algebra的可分解映射空间的预对偶

The predual of the space of decomposable maps from a $C^*$-algebra into a von Neumann algebra

Kyung Hoon Han

摘要:

对于$C^*$ -代数$\mathcal A$和von Neumann代数$\mathcal R$,我们刻画了从$\mathcal A$到$\mathcal R$的可分解映射空间$D(\mathcal A,\mathcal R)$的预对偶.该预对偶是$\mathcal A \otimes \mathcal R_*$上的矩阵正则算子空间结构,具有一定的泛性质.在$\mathcal A \otimes \mathcal R_*$上所有可能的矩阵正则算子空间结构中,在两个自然约束下,它的矩阵范数最大,它在每个矩阵层上的正锥最小:(1)对于$x\in M_k(\mathcal A), y \in M_l(\mathcal R_*)$,$|x \otimes y| \le |x| |y|$;(2)如果$v \in M_k(\mathcal A)^+$和$w \in M_l(\mathcal R_*)^+$,$v \otimes w$是正的.

英文摘要:

For a $C^*$-algebra $\mathcal A$ and a von Neumann algebra $\mathcal R$, we describe the predual of space $D(\mathcal A,\mathcal R)$ of decomposable maps from $\mathcal A$ into $\mathcal R$ equipped with decomposable norm. This predual is found to be the matrix regular operator space structure on $\mathcal A \otimes \mathcal R_*$ with a certain universal property. Its matrix norms are the largest and its positive cones on each matrix level are the smallest among all possible matrix regular operator space structures on $\mathcal A \otimes \mathcal R_*$ under the two natural restrictions: (1) $|x \otimes y| \le |x| |y|$ for $x\in M_k(\mathcal A), y \in M_l(\mathcal R_*)$ and (2) $v \otimes w$ is positive if $v \in M_k(\mathcal A)^+$ and $w \in M_l(\mathcal R_*)^+$.
