✦ Synopsis

In the exact propagator for finite temperature gluons the location of the transverse and longitudinal poles in the gluon propagator are unknown functions of wave vector: | T (k) and | L (k). The residues of the poles, also unknown, fix the normalization of the one gluon vector potential and thus of the field strength. The naive energy density E 9 } D 9 +B 9 } H 9 is not correct because of dispersion. By keeping the modulations due to the source currents the energy density is shown to be | T ÂV and | L ÂV regardless of the functional form of | T (k) and | L (k). The momentum density is kÂV. The resulting energy-momentum tensor is not symmetric.
