摘要: In this paper, we consider conformal metrics on a unit 4-disc with an asymptotically hyperbolic end and possible isolated conic singularities. We define a mass term of the AH end. If the σ 2 curvature has lower bound σ 2≥ 32 , we prove a Penrose type inequality relating the mass and contributions from singularities. We also classify sharp cases, which is the standard hyperbolic 4-space H4 when no singularity occurs. It is worth noting that our curvature condition implies non-positive energy density. This is joint work with Fang, Hao
