Introduction,The conformal group -the group of angle preserving transformations of a pseudo-Riemannian manifold -seems to be playing a fundamental role in nature, a role which is yet to be fully understood and appreciated.

The Conformal Group of a Conformally Flat Space Time and Its Twistor Representations,: U →’U of a neighbourhood U ⊂M onto ‘U⊂’M is said to be . if the corresponding tangent map φ. preserves the angles. In a slightly more technical language this means that for given coordinates X. and ’X.on U and ’U we have
