摘要：

The high-temperature limit of the three-graviton vertex function is studied in thermal quantum gravity, to one-loop order. The leading (T4) Contributions arising from internal gravitons are calculated and shown to be twice the ones associated with internal scalar particles, in correspondence with the two helicity states of the graviton. The gauge invariance of this result follows as a consequence of the Ward and Weyl identities obeyed by the thermal loops, which axe verified explicitly.
