摘要：

It is suggested that the fermion determinant for a vector-like gauge theory with strictly massless quarks can be represented on the lattice as det 1+V/2, where V = X((XX)-X-dagger)(-1/2) and X is the Wilson-Dirac lattice operator with a negative mass term. There is no undesired doubling and no need for any fine tuning. Several other appealing features of the formula are pointed out. (C) 1998 Elsevier Science B.V.
