The thermal self-energy of gluons generally depends on four Lorentz-invariant functions when the gauge-fixing condition is rotationally invariant. Only two of these occur in the hard thermal loop approximation of Braaten and Pisarski because of the abelian Ward identity K + 6 +& htl =0. For the exac
