Query: A new approach to Ginsparg-Wilson fermions   We expand the most general lattice Dirac operator D in a basis of simple
operators. The Ginsparg-Wilson equation turns into a system of coupled
quadratic equations for the expansion coefficients. Our expansion of D allows
for a natural cutoff and the remaining quadratic equations can be solved
numerically. The procedure allows to find Dirac operators which obey the
Ginpsparg-Wilson equation with arbitrary precision.
