It is mentioned that anyon thermodynamic potential Q(α,N) could not
be factorized in terms characteristic of the ideal boson α=0 and
fermion α=1 gases by the relation Q(α,N)=(1âα)Q(0,Nbâ)+αQ(1,Nfâ) in which N=Nfâ+Nbâ, that claimed in Phys. Rev. Lett. 78,
3233 (1997). Our analyses indicate that the thermodynamic quantities of anyon
gas may be factorized as Q(α)=αQ(1)+(1âα)Q(0) only in
the two-dimension system
