Improved cosmological parameters and treatment of the 5-dimensional Klein–Gordon field and Dirac-field on the basis of the Projective Unified Field Theory

The 5-dimensional Projective Unified Field Theory (PUFT) elaborated and further developed by the author since 1957 is a geometrical semi-unified field theory restricting to gravitation, electromagnetism and scalarism. Up till now the substrate (matter) was described on a 5-dimensional phenomenological continuum mechanics. But it proved rather important to investigate the Klein–Gordon field and the Dirac field within this 5-dimensional concept of PUFT in order to get a better insight into some relationships of continuum mechanics mentioned, particularly with respect to cosmology.
