摘要：
The thermal Green function D-mu nu(x) for free, massless gauge bosons is computed exactly in a variety of gauges (Feynman, covariant, Coulomb, and Landshoff-Rebhan). At large temporal separations it falls exponentially. At large spatial separations it falls like T/r. In contrast, the zero-temperature propagator falls quadratically in both regimes, being proportional to 1/(t(2) -r(2)).
