与图相关的C* 代数的稳定性

Stability of C*-algebras associated to graphs

Mark Tomforde

摘要:

给出了图C ~*-代数稳定性的五个等价条件,刻画了图C ~*-代数的稳定性.我们还证明了,如果G是一个无源图,那么C*(G)是稳定的当且仅当G中的每个顶点都可以被无穷多个顶点到达。我们利用这个刻画实现了图C* 代数的稳定化。具体地说,如果G是一个图,F是G的每个顶点加一个头所形成的图,则C*(F)是C*(G)的稳定化。

英文摘要:

We characterize stability of graph C*-algebras by giving five conditions equivalent to their stability. We also show that if G is a graph with no sources, then C*(G) is stable if and only if each vertex in G can be reached by an infinite number of vertices. We use this characterization to realize the stabilization of a graph C*-algebra. Specifically, if G is a graph and F is the graph formed by adding a head to each vertex of G, then C*(F) is the stabilization of C*(G).
