Highly Influential

We have carried out an analysis of ill-conditioning close to Schwartz singularities in Kohn variational calculations for (e + − H 2) scattering. Using a formal measure of distance to singularity, we discuss weaknesses in using the determinant of the Kohn matrix as a way of identifying regions likely to correspond to anomalous results. A simple method for… (More)
