On the ADM mass of critical area-normalized capacitors
摘要
In this note, we establish mass–capacity inequalities for asymptotically flat manifolds whose boundary capacity potential satisfies an overdetermined boundary condition—so-called critical area-normalized capacitors. As a consequence, we derive uniqueness results for the Schwarzschild metric and sharpen uniqueness theorems for spin asymptotically flat static vacuum spacetimes with a connected photon surface, as well as for spin asymptotically flat static manifolds satisfying an overdetermined Robin-type boundary condition.
