| Abstract: | Some years ago the author published a new version of a 5-dimensional Projective Unified Field Theory unifying gravitation, electromagnetism and scalarism. Geometrically this theory is mainly based on following 5-dimensional assumptions: symmetric metric tensor, Riemannian curvature, torsion, projector property of the basic quantities. A particular projection procedure leads from the 5-dimensional field equations and conservation laws to 4-dimensional ones. The 4-dimensional scheme of equations is interpreted physically. Special interest is taken in the energy projector, describing an electrically charged perfect fluid. Several physical predictions and applications are presented. |
