Abstract

We continue our study, begun in [7], into the stationary axisymmetric solutions of the Einstein vacuum equations containing two (or more) black holes. This problem reduces to an elliptic system of nonlinear partial differential equations with prescribed blow‐up as boundary conditions. We show the existence of solutions to the reduced system for any value of the five parameters of the problem. We show some regularity at the poles of the horizons. Using this result, we simplify the formula for the angle of deficiency of the conical singularity on the component of the axis of symmetry between the two horizons. This is to be interpreted as the gravitational force between rotating black holes. We also prove that the metrics constructed from solutions of the reduced system are indeed asymptotically flat.

The problem of two interacting charged particles in three dimensions, including effects of radiation reaction, is formulated abstractly and an existence/uniqueness theorem is proved for a suitable "initial segment problem." The delay-differential equations are treated in the cases of pure retarded a

The initial segment problem for two interacting charged particles is studied and errors are corrected in the author's previous paper on this problem. An existenceiuniqueness theorem holds for the forward extension under retarded interaction; a uniqueness theorem holds for the backward extension and

The effect of the radiation-pressure in the problem of the two bodies is analysed. It is found that such an effect is the same as that of reducing the stellar mass, m, by the factor p (0 5 p 5 1 ) . The case p < 0 leads to stellar instability and, consequently, it is not considered here. The problem
