摘要：

We summarize our results for the impact of anisotropic fermionic velocities in (2 + 1)-dimensional QED on the critical number of fermion flavors. N-f(c), and dynamical mass generation. We apply different approximation schemes for the gauge boson vacuum polarization and the fermion-boson vertex to analyze the Dyson-Schwinger equations in a finite volume. Our results point toward large variations of N-f(c) away from the isotropic point in agreement with other approaches. (C) 2011 Elsevier B.V. All rights reserved.
