We obtain the isoperimetric
profile for the standard initial slices in the Reissner–Nordstrom and Schwarzschild
anti-de Sitter spacetimes, following recent work of Bray and Morgan on isoperimetric
comparison. We then discuss these results in the context of Bray’s isoperimetric
approach to the Penrose inequality.
