Query: The classical double copy in maximally symmetric spacetimes   The classical double copy procedure relates classical asymptotically-flat
gravitational field solutions to Yang-Mills and scalar field solutions living
in Minkowski space. In this paper we extend this correspondence to maximally
symmetric curved spacetimes. We consider asymptotically (A)dS spacetimes in
Kerr-Schild form and construct the corresponding single and zeroth copies. In
order to clarify the interpretation of these copies, we study several examples
including (A)dS-Schwarzschild, (A)dS-Kerr, black strings, black branes, and
waves, paying particular attention to the source terms. We find that the single
and zeroth copies of stationary solutions satisfy different equations than
those of wave solutions. We also consider how to obtain Einstein-Maxwell
solutions using this procedure. Finally, we derive the classical single and
zeroth copy of the BTZ black hole.
