Abstract

We review dynamical mass generation in three and four dimensional Ableian gauge theories. The basic approach analyzed here is to solve Schwinger-Dyson equations in some approximations. In both cases, the coupling has to be larger than a critical value to have dynamical symmetry breaking. In QED₄, chiral symmetry is spontaneouly broken if α>α_c (≃ π/3) in ladder approximation. The electron becomes massive, and is realized as Skyrmion in the low energy effective action. In QED₃, electron gets dynmical mass in 1/N expansion if N
