单C* 代数的分类及高维非交换环面

Classification of simple C*-algebras and higher dimensional noncommutative tori

Huaxin Lin

摘要:

本文证明了迹拓扑秩为零的单C* 代数-代数可以用序$K$ -理论进行分类.我们应用这一分类结果表明,某些简单的交叉产品是同构的,如果他们有相同的有序$K$ -理论。特别地,$C({\mathbb T}^k)\times_θ{\mathbb Z}$形式的无理高维非交换环面实际上是圆代数的归纳极限。

英文摘要:

We show that unital simple C*-algebras with tracial topological rank zero which are locally approximated by subhomogeneous C^-algebras can be classified by their ordered $K$-theory. We apply this classification result to show that certain simple crossed products are isomorphic if they have the same ordered $K$-theory. In particular, irrational higher dimensional non-commutative tori of the form $C({\mathbb T}^k)\times_θ{\mathbb Z}$ are in fact inductive limits of circle algebras.
