摘要:In this preliminary work, I provide the outline of an argument (leaving the full proof to a future
publication) that there exists a valid renormalization group blocking transformation which converts
the continuum fermion action into a Ginsparg-Wilson lattice action. I construct the blocking
for the massless overlap operator as a specific example, indicating how other Ginsparg-Wilson
lattice Dirac operators can be derived in a similar fashion. This renormalization group transformation
modifies the gauge action and adds a number of irrelevant terms to the lattice action. The
procedure is not valid for lattice Dirac operatorswhich do not exactly satisfy the Ginsparg-Wilson
relation, for example the Wilson operator.
