WebOct 31, 2014 · Abstract. We present a generalization of the spinor and twistor geometry for (pseudo) Riemannian manifolds enabled with nonholonomic distributions or for … Web3 Twistor Space We begin our study of twistor space by introducing the two main field equations, and then proceed to give a definition of twistor space in terms of projective spaces. This will then let us examine the link between twistor space and spacetime through the twistor correspondence. 3.1 Zero Rest Mass & Twistor Equations We are familiar with …
