Query: Axial vector current of exact chiral symmetry on the lattice   We discuss the exact chiral symmetry and its spontaneous breakdown in lattice
QCD with the Dirac operators satisfying the Ginsparg-Wilson relation. The axial
vector current, which turns out to be related to the vector current simply by
the insertion of the operator \gamma_5 (1-aD), is explicitly constructed in the
case of the Neuberger-Dirac operator. We also consider an Euclidean proof of
the Nambu-Goldstone theorem using the Ward-Takahashi identity of this symmetry.
