Abstract

In particular cases of stationary and stationary axially symmetric space-time passage to non-relativistic limit of Einstein equation is completed. For this end the notions of absolute space and absolute time are introduced due to stationarity of the space-time under consideration. In this construction absolute time is defined as a function tt on the space-time such that \prtt\prt_t is exactly the Killing vector and the space at different moments is presented by the surfaces t=\cont=\con . The space-time metric is expressed in terms of metric of the 3-space and two potentials one of which is exactly Newtonian gravitational potential Φ\Phi, another is vector potential A\vec A which, however, differs from vector potential known in classical electrodynamics. In the first-order approximation on Φ/c2\Phi/c^2, A/c|\vec A|/c Einstein equation is reduced to a system for these functions in which left-hand sides contain Laplacian of the Newtonian potential, derivatives of the vector potential and curvature of the space and the right-hand sides do 3-dimensional stress tensor and densities of mass and energy.
