%TOn the statistical mechanics of the anyon gas
%XA perturbative computation of the grand partition function of an anyon gas at first and second order in the anyonic coupling constant {alpha} is reviewed. Particular care is taken of the nonanalytic behaviour of the thermodynamical potential in terms of {alpha}. To first order in {alpha} the results are strikingly simple: only the second virial coefficient gets perturbative corrections when computed close to bosonic statistics. At second order however, the complexity of the anyon model appears. As illustration the correction to the third virial coefficient is given. (K.A.) 18 refs.; 2 figs.; 2 tabs.
