Abstract
The salient features of the Ginsparg-Wilson fermion in topologically nontrivial background gauge fields are outlined. The R-invariance of the zero modes, the indices and the index theorem on a finite lattice are illustrated. The role of R in converting the nonlocal Dc into a sequence of highly local D is demonstrated.
