核$^*$ -代数及其全自由积的拓扑自由熵维数

Topological Free Entropy Dimensions in Nuclear C$^*$-algebras and in Full Free Products of C$^*$-algebras

Don Hadwin, Qihui Li, Junhao Shen

摘要:

本文引入了单位C $^*$代数中元素元组$n$的拓扑轨道维数的概念。利用这一概念,我们得到核C $^*$代数的任意一族自伴生成元的Voiculescu拓扑自由熵维数小于或等于1.我们还证明了单位C $^*$代数的全自由积的拓扑自由熵维数是可加的。在附录中,我们证明了Blackadar和Kirchberg的单位MF代数的单位全自由积也是MF代数。

英文摘要:

In the paper, we introduce a new concept of topological orbit dimension of $n$-tuples of elements in a unital C$^*$ algebra. Using this concept, we conclude that the Voiculescu's topological free entropy dimension of any family of self-adjoint generators of a nuclear C$^*$ algebra is less than or equal to 1. We also show that the topological free entropy dimension is additive in the full free products of unital C$^*$ algebras. In the appendix, we show that unital full free product of Blackadar and Kirchberg's unital MF algebras is also MF algebra.
