A comment on the index of the lattice Dirac operator and the Ginsparg-Wilson relation
Atsushi Yamada
We pursue Ginsparg and Wilsons' block spin approach in the derivation of the Ginsparg-Wilson relation and study the correspondence of the eigenmodes of the Dirac operators in the c…

A note on the exact lattice chiral symmetry in the overlap formalism
Yoshio Kikukawa, Atsushi Yamada
Using the grassman-number-integral representation of the vacuum overlap formula, it is shown that the symmetry of the auxiliary quantum fermion system in the overlap formalism indu…
