本文的目的是将Gauss映射,即连分式的Bernoulli移位,转移到非对易环境中。我们认为,F·博卡(F.Boca)和D·蒙迪奇(D.Mundici)分别考虑的AF代数{A}上是这样一个地图发挥作用的自然位置。$GA$的中心与$C[0,1]$同构,因此我们首先考虑高斯映射在$C[0,1]$上的作用,然后将该映射扩展到$\mathfrak{A}$,并表明该扩展继承了许多理想的性质。
The aim of this paper is to transfer the Gauss map, which is a Bernoulli shift for continued fractions, to the noncommutative setting. We feel that a natural place for such a map to act is on the AF algebra $\mathfrak{A}$ considered separately by F. Boca and D. Mundici. The center of $\ga$ is isomorphic to $C[0,1]$, so we first consider the action of the Gauss map on $C[0,1]$ and then extend the map to $\mathfrak{A}$ and show that the extension inherits many desirable properties.
