Gravitation theory in multi-messenger astronomy I: comparison of geometrical and field approaches to the physics of gravitational interaction Yu.V. Baryshev, S.A. Oschepkov

Abstract

     In modern theoretical physics there are two alternative possibilities of the description of gravitation: geometrical theory of the General Relativity Theory (GRT) of Einstein and non-metric theory of the material tensor Field Gravitation Theory (FGT) of Feynman. In this first report general provisions of these theories are stated: basic principles, Lagrangians, equations of the field and equations of the motion. These equations will be used for interpretations of observations in multimessenger astronomy, which discussed in our second report.
