Simple spinors as Urfelder

Since components of simple spinors in dimensions greater than five are functionally linked among themselves, one might want to find, starting from a Dirac equation, equations that contain only the independent ones; the outcome can only be highly non linear equations. It is tried here to test, instead, the possibility that such ''basic'' fields satisfy per se linear equations, each in its own space, and the consequences that this approach has on the simple spinors which derive from them. 9 refs
