The hyperbolic Penrose inequality is a mass-area comparison for initial data approaching a hyperbolic reference metric at infinity. In the time-symmetric formulation with
three-dimensional spherical infinity and cosmological constant , the scalar curvature
is at least
and the inner boundary is minimal
and outer area minimizing. The proposed bound is
where
and
counts all components of full enclosing cuts. The mass is the Lorentz norm of the
four hyperbolic metric fluxes,
, assumed future timelike.
These spatial fluxes are metric charges rather than ADM momentum.
