与分支覆盖相关的C* 代数-代数
C*-algebras associated with branched coverings
摘要：
本文将与分支覆盖相联系的C* 代数-代数作为广群C* 代数-代数和Cuntz-Pimsner代数来分析。我们确定条件时，代数是简单的，纯粹的无限。我们指出如何计算的K-理论的几个例子，包括一个有关的有理映射的黎曼球面。
英文摘要：
In this note we analyze the C*-algebra associated with a branched covering both as a groupoid C*-algebra and as a Cuntz-Pimsner algebra. We determine conditions when the algebra is simple and purely infinite. We indicate how to compute the K-theory of several examples, including one related to rational maps on the Riemann sphere.
