An affine field description of gravitation electromagnetism and matter.
An examination of the adequacy of the Affine Field Theory as a descriptive geometric structure for the representation of physical events. It is shown that the theory leads to a derivation of elemental matter from purely geometric considerations in an abstract affinely connected space and that it yields equations that describe mesonic phenomena in a "physical" space of four dimensions of the Riemann variety. The meson character arises solely from the interactions of gravitational and electromagnetic fields, where only geometric arguments enter into the Lagrangean function and where the field mass is an integration constant. In addition, it is shown that the theory also describes macroscopic matter. Maxwell-Lorentz electrodynamics, and gravitational fields interacting with uncharged matter in the absence of electromagnetic fields.
