| Abstract: | The infrared behaviour of the transversal gluon propagator in QCD at T≠0 is investigated within the ghost-free axial gauge. The singularities found in this propagator for the momentum p ～ g2T remain for any choice of the gauge and indicate the infrared instability of QCD at finite temperatures. |
