满足能量条件的渐近$AdS_2\times S^2$度量

Asymptotically $AdS_2\times S^2$ metrics satisfying the Null Energy Condition

Paul Tod

摘要:

我们找到了与Galloway和Graf \cite{GG}约束渐近$AdS_2\times S^2$时空(和可微性假设)的结果相容的最一般的度量分析,然后研究了它在各种几何和物理限制下的曲率.特别是,我们找到明确的例子,这是渐近的$AdS_2\times S^2$度量,在\cite{GG}的意义上,并满足能量条件,但不同于$AdS_2\times S^2$。

英文摘要:

We find the most general metric ansatz compatible with the results of Galloway and Graf \cite{GG} constraining asymptotically $AdS_2\times S^2$ space-times (and a differentiability assumption), and then study its curvature subject to a variety of geometrical and physical restrictions. In particular we find explicit examples which are asymptotically $AdS_2\times S^2$ metrics, in the sense of \cite{GG}, and which satisfy the Null Energy Condition but which differ from $AdS_2\times S^2$.
