摘要：
Numerical results for the transport coefficients of quark gluon plasma are obtained by lattice simulations on on 16(3) x 8 lattice with the quench approximation where we apply the gauge action proposed by Iwasaki. The bulk viscosity is consistent with zero, and the shear viscosity is slightly smaller than the typical hadron masses. They are not far from the simple extrapolation on the figure of perturbative calculation in high temperature limit down to T similar to T-c. The gluon propagator in the confined and deconfined phases are also discussed.
