  In this paper we analyse the perturbative aspects of Chern-Simons field
theories in the Coulomb gauge. We show that in the perturbative expansion of
the Green functions there are neither ultraviolet not infrared divergences.
Moreover, all the radiative corrections are zero at any loop order. Some
problems connected with the Coulomb gauge fixing, like the appearance of
spurious singularities in the computation of the Feynman diagrams, are
discussed and solved. The regularization used here for the spurious
singularities can be easily applied also to the Yang-Mills case, which is
affected by similar divergences.
