Query: Dynamical Mass Generation in QED3 with Chern--Simons Term   In (2+1)-dimensional QED with a Chern-Simons term, we study dynamical
breaking of chiral symmetry, using the Dyson--Schwinger equation for the
fermions. There is a region in parameter space were dynamical chiral symmetry
breaking occurs, just as in pure QED3 (without Chern--Simons term); outside
this region, this chiral symmetry breaking solution does not exists. Our
results, both numerically and analytically, show that the chiral phase
transition is a discontinuous first-order transition.
