我们考虑有限温度下AdS中的弱耦合QFT。在边界理论中计算了标量算符的全息热两点函数。我们提出的解析表达式，由于本地四次相互作用的散装，与任意数量的衍生物和任何数量的时空维度的领先的修正。解决方案是固定的明智地挑选一个anomaly和施加一致性条件。这些条件包括解析性质，与算子乘积展开的一致性，以及Kubo-Martin-Schwinger条件。对于没有任何衍生物的情况下，我们显示协议与明确的图解计算。答案的结构暗示了热梅林振幅。此外，我们推导出一个简单的热两点函数的色散关系，重建的功能从其不连续性。
We consider weakly-coupled QFT in AdS at finite temperature. We compute the holographic thermal two-point function of scalar operators in the boundary theory. We present analytic expressions for leading corrections due to local quartic interactions in the bulk, with an arbitrary number of derivatives and for any number of spacetime dimensions. The solutions are fixed by judiciously picking an ansatz and imposing consistency conditions. The conditions include analyticity properties, consistency with the operator product expansion, and the Kubo-Martin-Schwinger condition. For the case without any derivatives we show agreement with an explicit diagrammatic computation. The structure of the answer is suggestive of a thermal Mellin amplitude. Additionally, we derive a simple dispersion relation for thermal two-point functions which reconstructs the function from its discontinuity.
