Field theory approach to gravitation.
Abstract
Mathematical equations for a fieldtheory approach to gravitation are obtained by starting with the fieldtheory requirement that the volume force be the covariant divergence of a field stressenergy. Conservation relations are derived in the form of the consistency conditions of the equations, and the equations are solved iteratively for the static centralbody case. The numerical value of a certain parameter entering into the equation for the total stressenergy is determined on the basis of several physical arguments. It is concluded that general relativity is only a member of a more general class of field theories and that a fieldtheory approach to gravitation does not inevitably lead to Einstein's general theory of relativity.
