摘要：We present Monte Carlo results for the thermodynamics of pure SU(N) gauge theories with N = 2, ...,6 in 2+1 dimensions. We focus on the confined phase region T < Tc and study thermodynamics variables such as the trace of the energy-momentum tensor, pressure, energy and entropy density using the integral method. We also investigate scaling properties with N of the different observables. We compare our results with a gas of free glueballs and the bosonic string predictions for the Hagedorn spectrum.
