A. Hoferichter et al., PSEUDOSCALAR CORRELATORS AND THE PROBLEM OF THE CHIRAL LIMIT IN THE COMPACT LATTICE QED WITH WILSON FERMIONS, Nuclear physics. B, 1995, pp. 669-671
The phase diagram for the compact lattice QED with Wilson fermions is
shown. We discuss different methods for the calculation of the 'pion'
mass m(pi) near the chiral transition point kappa(c)(beta).
