Oguzhan Demirel : Degenerate Lambert quadrilaterals and Möbius transformations, 409-415

Abstract:

We present a new characterization of Möbius transformations by using a new geo-metric concept that we will call "degenerate Lambert quadrilateral". Our proof is based on a geometric approach.

Key Words: Lambert quadrilateral, Möbius transformation.
