The range of linear fractional maps on the unit ball
The range of linear fractional maps on the unit ball
In 1996, C. Cowen and B. MacCluer studied a class of maps on $\mathbb C^N$ that they called linear fractional maps. Using the tools of KreÄn spaces, it can be shown that a linear fractional map is a self-map of the ball if and only if an associated matrix is …
