We also provide a closed loop equation for the spectral function of the energy-momentum tensor in terms of the gluon spectral function. This setup is then used for computing the shear viscosity over entropy ratio $\\eta/s$ in a temperature range from about $0.4\\, T_c$ to $4.5\\, T_c$. The ratio $\\eta /s$ has a minimum at about $1.25\\, T_c$ with the value of about 0.115. We also discuss extensions of the present results to QCD.","authors_text":"Jan M.
