拓扑箭图

Topological Quivers

Paul S. Muhly, Mark Tomforde

摘要:

拓扑箭图是有向图的推广,其中顶点和边的集合是局部紧的T2空间。与这样的拓扑代数Q相关联的是一个C*-对应,从这个对应可以构造一个Cuntz-Pimsner代数C*(Q)。在本文中,我们发展的一般理论的拓扑结构的C* 代数,并显示如何某些C* 代数在文献中发现可以从这个一般的角度来看。特别地,我们证明了拓扑箭图的C* 代数推广了研究得很好的图C* 代数类,并且与该理论类似,C*(Q)的大部分算子代数结构可以由Q确定。我们还表明,许多基本的结果,从理论的图C* 代数有自然的类似物的情况下,拓扑箭图(往往与更多的涉及证明)。这些理论包括规范不变唯一性定理、Cuntz-Krieger唯一性定理、理想结构的描述和简化条件。

英文摘要:

Topological quivers are generalizations of directed graphs in which the sets of vertices and edges are locally compact Hausdorff spaces. Associated to such a topological quiver Q is a C*-correspondence, and from this correspondence one may construct a Cuntz-Pimsner algebra C*(Q). In this paper we develop the general theory of topological quiver C*-algebras and show how certain C*-algebras found in the literature may be viewed from this general perspective. In particular, we show that C*-algebras of topological quivers generalize the well-studied class of graph C*-algebras and in analogy with that theory much of the operator algebra structure of C*(Q) can be determined from Q. We also show that many fundamental results from the theory of graph C*-algebras have natural analogues in the context of topological quivers (often with more involved proofs). These include the Gauge-Invariant Uniqueness theorem, the Cuntz-Krieger Uniqueness theorem, descriptions of the ideal structure, and conditions for simplicity.
