Abstract

The problem of the gauge dependence of the fermion mass in the Maxwell-Chern-Simons QED2+1_{2+1} is revisited. Using Proca mass term as an intermediate infrared regulator we are demonstrating gauge-invariance of the fermion mass shell in QED2+1_{2+1} in all orders of the perturbation theory.
