Numerical Methods for the QCD Overlap Operator: II. Optimal Krylov Subspace Methods

G. Arnold, N. Cundy, J. van den Eshof +4

We investigate optimal choices for the (outer) iteration method to use when solving linear systems with Neuberger's overlap operator in QCD. Different formulations for this operato…
