Critical Behavior of ($2 + 1$)-Dimensional QED: $1/N$ Expansion

Abstract : We present recent results on dynamical chiral symmetry breaking in (2 + 1)-dimensional QED with N four-component fermions. The results of the 1 / N expansion in the leading and next-to-leading orders were found exactly in an arbitrary nonlocal gauge.
