Abstract
The theory of the magnetic catalysis of chiral symmetry breaking in QED is developed. An approximation for the Schwinger-Dyson equations describing re liably this phenomenon is established, i.e. it is shown that there exists a consistent truncation of those equations in this problem. The equations ar e solved both analytically and numerically, and the dynamical mass of fermi ons is determined. (C) 1999 Elsevier Science B.V. All rights reserved.
