Abstract
It is shown that quenched QED in dimensions D < 4 has solutions which violate chiral symmetry for all values of the coupling. The equation for the fermion mass function in the rainbow approximation as well as with the Curtis-Pennington vertex is studied thoroughly, both analytically and numerically. In particular, we demonstrate how to extract the critical coupling α c relevant in four dimensions from the D dimensional theory.
