本文考虑了欧氏BTZ黑洞背景或等价热AdS_3背景的单圈配分函数,这些背景是H_3(Euclidean AdS_3)的等价物。单圈配分函数是模不变的,我们可以读出与hep-th/0001053中发现的一致的谱。我们看到的长弦和离散态与预期一致。
We consider the one-loop partition function for Euclidean BTZ black hole backgrounds or equivalently thermal AdS_3 backgrounds which are quotients of H_3 (Euclidean AdS_3). The one-loop partition function is modular invariant and we can read off the spectrum which is consistent to that found in hep-th/0001053. We see long strings and discrete states in agreement with the expectations.
