Conformal mapping from polygon with circle segments

[Kurret]

I am looking for a conformal map from a "polygon" to eg the upper half plane, which consists of circle segments instead of lines. So for example, it could be a quadrilateral ABCD, but where AB is a circle segment. The closest I can find is the Schwarz-Christoffel mapping.

Anyone has any tips?

I don't know about this subject, but I notice that you can find numerous hits by searching for the topic of conformal mapping and "circular arc polygons". (For example: http://en.wikipedia.org/wiki/Schwarzian_derivative mentions circular arc polygons.)

If you find a reference that seems to do what you want and have a specific question about it, there are probably forum members who can explain it.
