Query: Hard thermal loops in long wave-length and static external gravitational
  fields   We study, in the long wave-length and static limits, the structure of the
n-point graviton functions at high temperature. Using the gauge and Weyl
invariance of the theory, we derive a simple expression for the hard thermal
amplitudes in these two limits.
