It is shown that it is a general consequence of these features that the Poincaré invariance is broken down to the Lorentz one, so indicating that it is not possible to keep simultaneously the free nature of the anyon and the translational invariance.225-230engArtigo10.1016/0370-2693(94)01445-IWOS:A1995QD82300034Acesso restrito2-s2.0-000073157082793938764156086314084638411003
