Generating Conjecture and Some Einstein-Maxwell Field of High Symmetry

For stationary cylindrically symmetric solutions of the Einstein-Maxwell equation we have shown that the "charged" solutions of McCrea, Chitre et al.(CGN), Van den Bergh and Wils (VW) can be obtained from the seed metrics using generating conjecture. The McCrea "charged" solution has as a seed vacuum metric the Van Stockum solution with a Killing vector (0,0,1,0). The CGN "charged" solution and the VW "charged" solution have the static seed metrics connected by the complex substitution (t --> iz), (z --> it) and the Killing vector which is a simple linear combination of ${\partial}_ϕ$ and ${\partial}_{t}$ Killing vectors (VW), respectively ${\partial}_ϕ$ and ${\partial}_{z}$ Killing vectors (CGN).

The Kerr-Schild ansatz for the Nariai spacetime and the generating conjecture

We will show that the Nariai metric, i.e. the static spherically symmetric vacuum spacetime with a cosmological constant, admits a conformally Kerr-Schild spacetime representation. We find the vacuum solutions of the Einstein-Maxwell equations for the Nariai metric using the Horsky-Mitskievich generating conjecture.
