- Published 1998

We study three practical implementations of the Overlap-Dirac operator D/ o = 1 2 [1 + γ5ǫ(Hw)] in four dimensions. Two implementations are based on different representations of ǫ(Hw) as a sum over poles. One of them is a polar decomposition and the other is an optimal fit to a ratio of polynomials. The third one is obtained by representing ǫ(Hw) using… CONTINUE READING
