By Noah NissaniBased in the Noah Nissani and Elhanan Leibowitz's papers that appear in the bibliography. AbstractThe tensorial expression for the gravitational energy-momentum proposed by Nissani and Leibowitz [N & L, 91, 92] is thoroughly presented and used in calculating the integral gravitational energy in the surrounding of a star, and the fall velocity […]

LIKE-INERTIAL GLOBALLY PREFERRED FRAMES IN GENERAL RELATIVITY
By Noah NissaniBased in the Noah Nissani and Elhanan Leibowitz's papers that appear in the bibliography. Abstract Like-inertial global preferred frames, the non-rotating frames, are derived from the energy-momentum distribution by a variational procedure. It is shown that these global preferred frames, wherein the energy-momentum is globally conserved, share the experimental features […]
