对合算子代数的完全有界特征

Completely Bounded Characterization of Operator Algebras with Involution

Nikolay P. Ivankov

摘要:

本文研究了算子代数上的完全有界反同构,它们与对合的性质类似,只是性质是完全等距的。本文详细阐述了算子代数的Blecher特征定理,使其适用于具有完全有界自反同构的算子$K$ -代数。我们还建立了一个连接,这一结果与光滑$C^*$ -模块的概念,发挥了重要作用,在梅斯兰的方法Baaj-Julg图片的$KK$ -理论。

英文摘要:

In this paper we study the completely bounded anti-isomorphisms on operator algebras, that work similarly to the involutions with the exception for the property of being completely isometric. We elaborate the Blecher's characterization theorem for operator algebras to make it applicable to the so-called operator $K$-algebras with completely bounded reflexive anti-isomorphism. We also establish a connection of this result with the notion of smooth $C^*$-modules, that play an important role in Mesland's approach to Baaj-Julg picture of $KK$-theory.
