HIGH-TEMPERATURE QCD AND THE CLASSICAL BOLTZMANN-EQUATION IN CURVED SPACETIME

It has been shown that the high-temperature limit of perturbative ther mal QCD is easily obtained from the Boltzmann transport equation for ' 'classical'' coloured particles [P.F. Kelly et al., Phys. Rev. D 50 (1 994) 4209]. We generalize this treatment to curved space-time. We are thus able to construct the effective stress-energy tenser. We give a c onstruction for an effective action. As an example of the convenience of the Boltzmann method, we derive the high-temperature 3-graviton fun ction. We discuss the static case.
