arXiv:hep-lat/9810064 · doi:10.1016/S0370-2693(99)00318-4

Abstract

We compute Neuberger's overlap operator by the Lanczos algorithm applied to the Wilson-Dirac operator. Locality of the operator for quenched QCD data and its eigenvalue spectrum in an instanton background are studied.

Revised version: 16 pages, 5 figures, algorithm added
