Beschreibung:
  • Let (script M sign, g) be a strongly causal space-time, dim script M sign ≥ 3. Let f: script M sign → script M sign be a bijection such that images and pre-images of null geodesics (as point sets) are null geodesics. Then f is a conformal transformation. © 1998 American Institute of Physics.
