UCT-Kirchberg代数的核维数为1

UCT-Kirchberg algebras have nuclear dimension one

Efren Ruiz, Aidan Sims, Adam P. W. Sørensen

摘要:

我们证明了UCT类中的每个Kirchberg代数都有核维数为1。我们首先表明,Kirchberg 2-图代数平凡的$K_0$和有限的$K_1$有核维数为1,通过调整技术开发的Winter和Zacharias的Cuntz代数。然后证明了UCT类中的每个Kirchberg代数都是2-图代数的直极限,从而得到了我们的主要定理。

英文摘要:

We prove that every Kirchberg algebra in the UCT class has nuclear dimension 1. We first show that Kirchberg 2-graph algebras with trivial $K_0$ and finite $K_1$ have nuclear dimension 1 by adapting a technique developed by Winter and Zacharias for Cuntz algebras. We then prove that every Kirchberg algebra in the UCT class is a direct limit of 2-graph algebras to obtain our main theorem.
