完全有界核

Completely bounded kernels

Tirthankar Bhattacharyya, Michael A. Dritschel, Christopher S. Todd

摘要:

我们引入取值于L(A,B)的完全有界核,其中A和B是C* 代数.我们表明,如果B是内射这样的内核有一个Kolmogorov分解时,他们可以缩放到完全压缩,这是自动的,当索引集是可数的。

英文摘要:

We introduce completely bounded kernels taking values in L(A,B) where A and B are C*-algebras. We show that if B is injective such kernels have a Kolmogorov decomposition precisely when they can be scaled to be completely contractive, and that this is automatic when the index set is countable.
