Triple

Target class: bijection of the Riemann sphere
Context triple: [Möbius transformation, instanceOf, bijection of the Riemann sphere]

• A. extended complex plane
  The extended complex plane is the complex number system augmented with a single point at infinity, forming a compact space often visualized as the Riemann sphere.
• B. bounded symmetric domain (up to biholomorphism)
  A bounded symmetric domain (up to biholomorphism) is a connected bounded open subset of complex Euclidean space whose biholomorphic automorphism group acts transitively and admits, at each point, an involutive automorphism reversing all geodesics through that point, considered up to biholomorphic equivalence.
• C. homeomorphism chosen
  A homeomorphism is a continuous bijective function between topological spaces whose inverse is also continuous, establishing a topological equivalence between them.
• D. conformal model of the hyperbolic plane
  A conformal model of the hyperbolic plane is a geometric representation (such as the Poincaré disk or upper half-plane) in which hyperbolic lines and distances are depicted so that angles are preserved while the metric differs from the Euclidean one.
• E. self-homeomorphism of a surface
  A self-homeomorphism of a surface is a continuous bijection from the surface to itself with a continuous inverse, preserving its topological structure.
• F. None of above.
