$AdS_3$中新质量引力的相容边界条件

Consistent Boundary Conditions for New Massive Gravity in $AdS_3$

Yan Liu, Ya-Wen Sun

摘要:

本文研究了渐近$AdS_3$时空中新的质量引力理论的边界条件。我们发现,Brown-Henneaux边界条件与新的质量引力是一致的,对于所有的质量参数值。在中心荷消失的临界点,守恒荷也消失了。这提供了进一步的证据,该理论可能是平凡的布朗-亨诺边界条件下的临界点。对对数边界条件也进行了检验,发现对于这种新的质量重力理论,可以有三种对数边界条件,每种边界条件在临界点处都是一致的,而对于其它质量参数值,对数重力边界条件是不一致的。

英文摘要:

In this note we study the boundary conditions for the new massive gravity theory in asymptotically $AdS_3$ spacetime. We find that the Brown-Henneaux boundary conditions are consistent with the new massive gravity for all any value of the mass parameter. At the critical point where the central charge vanishes, the conserved charges vanish, too. This provides further evidence that the theory may be trivial at the critical point under Brown-Henneaux boundary conditions. The log boundary conditions are also examined and we find that we can have three kinds of log boundary conditions for this new massive gravity theory, each of which could be consistent at the critical point, while for other value of the mass parameter, the log gravity boundary condition is not consistent.
