abstract: 'The effects of the sample’s boundaries in the magnetic response of the charged anyon fluid at finite temperature are investigated. For the case of an infinite-strip sample it is shown that the Meissner effect takes place at temperatures lower than the fermion energy gap $\omega _{c}$. The temperature dependence of the corresponding effective penetration depth is determined. At temperatures much larger than the scale $\omega _{c}$, a different phase is found, in which the external magnetic field penetrates the fluid.'

Introduction
============

Recently much attention has been given to lower dimensional gauge theories. Such remarkable results as the chiral symmetry breaking [@1], quantum Hall effect [@2], spontaneously broken Lorentz invariance by the dynamical generation of a magnetic field [@3], and the connection between non-perturbative effects in low-energy strong interactions and QCD$%
_{2}$ [@4], show the broad range of applicability of these theories.

In particular, 2+1 dimensional gauge theories with fractional statistics -anyon systems [@4a]- have been extensively studied. One main reason for such an interest has
