Relativistic theory of gravity

Main principles of the relativistic theory of gravity (RTG) are presented. They include the following physical requirements: 1. Minkowski space is a fundamental space for all physical fields, including gravitational one. 2. Gravitational field is described by symmetrical tensor of the second rank and represents the real physical field, possessing density of energy-momentum. 3. Observation of geometrization principle and conditions of construction of gravitational field Lagrangian density, as quadratic function of covariant derivatives of the first order
