我们应用最近的建议，定义保守的质量渐近德西特时空类的陶伯-博尔特-德西特时空。我们计算了这些时空的作用量、熵和守恒质量，发现在某些情况下，质量和熵可以超过纯德西特时空的质量和熵，这违反了最近提出的相反的假设。
We apply a recent proposal for defining conserved mass in asymptotically de Sitter spacetimes to the class of Taub-Bolt-de Sitter spacetimes. We compute the action, entropy, and conserved mass of these spacetimes, and find that in certain instances the mass and entropy can exceed that of pure de Sitter spacetime, in violation of recent suggestive conjectures to the contrary.
