Spinor geometry

A geometry is constructed which defines a spinor and the coordinate x(mu) in Minkowski space in terms of spinor products. It is shown that the space associated with this geometry is a Friedmann space and that the coordinate x(mu) is a Friedmann coordinate. The system of gravitational field equations is closed. The theory includes eight real functions which define both the reference system and the coordinate grid. The theory permits space-time quantization and eliminates the difficulties associated with the problem of inertia and the absolute nature of flat space-time.
