Lectures on the theory of relativity and gravitation: Contemporary analysis of the problem

Following Minkowski's ideas, it is shown that the essence and fundamental content of relativity theory lie in the unity of space-time, whose geometry is pseudo-Euclidean. In the framework of relativity theory and the geometrization principle, a relativistic theory of gravitation is developed which is claimed to explain all existing gravitational experiments and to offer new hypotheses on universe evolution and gravitational collapse.
