Conservation Laws and Preferred Frames in Relativistic Gravity. I. Preferred-Frame Theories and an Extended PPN Formalism
Abstract
We present and discuss a revised version of the Parametrized Post-Newtonian (PPN) Formalism. By regrouping the old PPN parameters, we obtain a new set of parameters which are used to classify theories of gravity according to four attributes; curvature of space-geometry, nonlinearity of gravity, existence of a preferred Universal rest-frame, and validity of conservation laws for momentum. We study a variety of preferred-frame theoiies of gravity, and show that new terms must be added to the PPN metric in order to analyze such prdened-frame theories from any chosen frame of reference. These new terms depend on the velocity of the observer's chosen frame relative to the preferred Universal rest-frame singled out by such theories.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
