本文指出球配分函数单圈引力修正中的相位因子引发状态计数解释的困惑，证明引入观察者后该相位大部分被抵消，仅剩总的负号。
摘要：
球配分函数是最简单的欧几里得引力计算之一。它通常被解释为状态计数。然而，单圈引力修正包含一个依赖维度的相位因子 $i^{D+2}$，这对于这种解释来说似乎令人困惑。我们证明，在包含观察者之后，对于应该对应于状态计数的量，该相位大部分被抵消。然而，一个总的负号仍然存在。
英文摘要：
The sphere partition function is one of the simplest euclidean gravity computations. It is usually interpreted as count of states. However, the one loop gravity correction contains a dimension dependent phase factor, $i^{D+2}$, which seems confusing for such an interpretation. We show that, after including an observer, this phase gets mostly cancelled for the quantity that should correspond to a count of states. However, an overall minus sign remains.
