An Interpretation of the Laws of Gravity and Inertia

Ideas on a source of inertia from fixed stars have crossed Physics least Mach onwards. Equations Maxwell-like for gravitation and inertia were obtained by several authors as a subspecies of the simplified theory of General Relativity. A precursor was Dennis Sciama. Introducing a four-potential, I submit here a tentative interpretation of our laws about gravity and inertia, in complete analogy with electromagnetism. In classical mechanics is not introduced, usually, a four potential. The field produced by this four-potential describes both gravitational and inertial Admit the gauge transformation on potential is equivalent to enunciate the equivalence principle, and vice versa. Inertial forces (ex. Coriolis force) are interpreted as a field action. All the inertia is interpreted as a field action. The physical presence of this field seems to be a fact, even more concrete the usual admission of inertial fictitious forces.
