Query: Fractal basins and chaotic trajectories in multi-black hole space-times   We investigate the phase-space for trajectories in multi-black hole
spacetimes. We find that complete, chaotic geodesics are well described by
Lyapunov exponents, and that the attractor basin boundary scales as a fractal
in a diffeomorphism invariant manner.
