Mass Formula for a Stationary Axisymmetric Configuration and the Physical Realization of the Kerr Metric
R. M. Avakian, G. Oganessyan
Abstract
We analyse the expression for the mass of a stationary axisymmetric configuration in general relativity obtained in our previous work [1]. From the generality of our formula and its incompatibility with the corresponding expression in Kerr space-time we argue that a stationary equilibrium distribution of a real matter cannot be a source of the Kerr metric.
