核C* 代数的扰动

Perturbations of nuclear C*-algebras

Erik Christensen, Allan Sinclair, Roger Smith, Stuart White, Wilhelm Winter

摘要:

Kadison和Kastler在可分希尔伯特空间上的所有有界算子的C*-子代数的集合上引入了一个自然度量。他们证明了充分闭代数是酉共轭的。当一个代数是可分的且有核的时,我们建立了这个猜想。我们也考虑这些概念的片面版本,我们从涉及可分核C* 代数的某些近包含中得到嵌入。在本文的最后,我们展示了我们的方法如何导致改进的一些类型的代数,目前感兴趣的分类程序的特征。

英文摘要:

Kadison and Kastler introduced a natural metric on the collection of all C*-subalgebras of the bounded operators on a separable Hilbert space. They conjectured that sufficiently close algebras are unitarily conjugate. We establish this conjecture when one algebra is separable and nuclear. We also consider one-sided versions of these notions, and we obtain embeddings from certain near inclusions involving separable nuclear C*-algebras. At the end of the paper we demonstrate how our methods lead to improved characterisations of some of the types of algebras that are of current interest in the classification programme.
