A ring structure on \({\mathcal Z}_ 0({\mathbb{C}}^ 4)\) and an inverse twistor function formula
The well-known Penrose's integral formula allows to express each free spinorial field verifying the Dirac equation by a ''twistorial function''. The present paper gives conversely an explicit way to compute a twistorial function associated to a field.
