摘要: We investigate solutions that are dynamically evolving between asymptotically de Sitter and anti-de Sitter regions in the context of Einstein gravity coupled to general matter fields d dimensions. find evidence there no such when content theory is `reasonable', i.e., weak energy condition satisfied. show exist for which conditions violated a finite region spacetime. speculate on holographic interpretation these gravitational backgrounds by combining ideas from AdS/CFT dS/CFT dualities.
