摘要：

The free energy density of the SU(3) gauge theory at temperatures T/T-c = 4/3,3/2 and 2 is calculated on lattices with temporal extent as small as N-tau = 2, 3 and spatial extent N-sigma = 4N(tau) using parametrized fixed point actions. Although cut-off effects are seen, they are hugely suppressed with respect to Wilson and Symanzik-improved actions and at N-tau = 3 there is already a good agreement with the continuum limit as extrapolated from the results with the Wilson action at N-tau = 6 and 8.
