Equilibrium Of Three Collinear Kerr Particles

The equilibrium problem of three collinear Kerr particles is studied within the framework of an exact solution of Einstein's equations. The system of conditions defining the equilibrium of the particles is derived in an explicit form and particular equilibrium configurations involving black-hole and hyperextreme constituents are considered. It is demonstrated that in some equilibrium states a spinning particle can exhibit combined properties characteristic both of black holes and hyperextreme objects.
