They also contain constructions of fundamental regions. There are two basic constructions: one is called a Ford fundamental region, another Dirichlet fundamental region. | |
Feb 4, 2023 at 19:49 | comment | added | p6majo | I tried to buy the book by Ford. But I can only find it in the US not shipable to Europe. On the other hand, I found the first 25 pages of the book at googlebooks. Within these 25 pages the isometric circle is discussed, which happens to be exactly the border of the two discs $D_1$ and $D_2$ for the example I showed in the question. Can I generalize this observation, that the fundamental domain is $\mathbb{C}$ with the discs removed that are surrounded by the isometric circles of $a$ and its inverse $a^{-1}$? This would be very neat and simple as well. | |
