Etymology
Named for German mathematician and theoretical astronomer August Ferdinand Möbius (1790–1868).
Noun
Möbius transformation (plural Möbius transformations)
- (geometry, complex analysis) A transformation of the extended complex plane that is a rational function of the form f(z) = (az + b) / (cz + d), where a, b, c, d are complex numbers such that ad − bc ≠ 0; an automorphism of the complex projective line.
