The charged spacetime Penrose inequality in upper-area form for Einstein-Maxwell initial data

Principal (Theorem 2.3): for one-ended three-dimensional data with arbitrary KK, nonzero ADM momentum, disconnected weakly future trapped boundary and the stated decay, m≥∣Q∣m\ge|Q| and rA≤m+m2−Q2r_A\le m+\sqrt{m^2-Q^2} with AA the minimal enclosing area; positive area and timelike ADM vector are conclusions. Equality (for m>∣Q∣m>|Q|, connected outermost horizon) identifies the data as a slice of dyonic Reissner-Nordstrom. Companions: the purely electric case in every dimension n≥4n\ge4; a Kerr-Newman Penrose inequality for axisymmetric electrovacuum exteriors with zero ADM momentum that assumes the area condition A≥4πQ4+4J2A\ge4\pi\sqrt{Q^4+4J^2}; and counterexamples to the Kerr-Newman bound when JJ is the bare gravitational angular momentum and fields decay only like r−2r^{-2}. Not shown: magnetic charge in dimensions four and up, or a general rotating inequality.
