ISU - Multigrid for computing propagators

Abstract

The Iteratively Smoothing Unigrid algorithm (ISU), a new multigrid method for computing propagators in Lattice Gauge Theory, is explained. The main idea is to compute good (i.e. smooth) interpolation operators in an iterative way. This method shows no critical slowing down for the 2-dimensional Laplace equation in an SU(2) gauge field. First results for the Dirac-operator are also shown. ((orig.)).
