摘要: Twistors correspond to well defined geometrical objects in spacetime. They can be completely described as members of the multi-vector algebra spacetime and then terms standard Clifford Cl1,3 corresponding space R 1,3. Their usefulness stands from two basic characteristics: first is existence twistor program Penrose [1] where they are used generate idea from, assumed, primitive elements (the twistors); second fact that spinors a representation with spin 1/2 Lorentz group L trivial, invariant, translations P, whereas twistors also but faithful group, not trivial representations full Poincare therefore indeed simplest which construction physical theory provide {L,P}.
