Projection of bisectors in a visual sphere

Click on a picture to see it in full screen.

The pictures show the projection of the bisectors bounding a Dirichlet domain into the visual sphere of a point in the complex hyperbolic plane. The point is the fixed point of an element U of PU(2,1), which has finite order. You can see my PhD thesis (end of Chapter 4) for all the information about the picture.

These pictures were made with SAGE
