Abstract:We construct a time-symmetric asymptotically flat initial data set to the Einstein-Maxwell Equations which satisfiesMediaObjects/s00220-005-1355-0flb1.gifwhere m is the total mass, MediaObjects/s00220-005-1355-0flb2.gif is the area radius of the outermost horizon and Q is the total charge. This yields a counter-example to a natural extension of the Penrose Inequality for charged black holes.The research of the first author was supported in part by NSF Grant DMS-0205545.The research of the second author was supported in part by NSF Grant DMS-0222387.
