I will discuss an invariant, the spherical volume of Besson-Courtois-Gallot, and a corresponding Plateau problem. For hyperbolic manifolds, the spherical volume was computed by Besson-Courtois-Gallot to be a multiple of the hyperbolic volume. Their arguments will be explained. We will also see that there is a unique Plateau solution given by the hyperbolic metric, up to intrinsic isometry.
