英文摘要
We investigate dynamics of inhomogeneous spacetime with a cosmological constant and find a universal picture : There is a critical value of the Abbott-Deser mass, beyond which localized inhomogeneities do not collapse into black holes. Consequently, black holes with large mass cannot be formed in the asymptotically de Sitter space-time, unless a naked singularity is formed. This result suggests a possible inflationary scenario for inhomogeneous universes.
