Abstract
We study chiral symmetry breaking in quenched QED4, using a vertex ans atz recently proposed by Curtis and Pennington. Bifurcation analysis i s employed in a general covariant gauge to investigate the gauge-depen dence of the critical coupling for chiral symmetry breakdown. This tur ns out to be relatively minor, justifying the use of this vertex.
