Query: General Dynamics of Spinors   In this paper, we consider a general twisted-curved space-time hosting Dirac
spinors and we take into account the Lorentz covariant polar decomposition of
the Dirac spinor field: the corresponding decomposition of the Dirac spinor
field equation leads to a set of field equations that are real and where
spinorial components have disappeared while still maintaining Lorentz
covariance. We will see that the Dirac spinor will contain two real scalar
degrees of freedom, the module and the so-called Yvon-Takabayashi angle, and we
will display their field equations. This will permit us to study the coupling
of curvature and torsion respectively to the module and the YT angle.
