The purpose of the paper is threefold: Ε½ . 1 To develop a useful error bound for the method of alternating projections which is relatively easy to compute and remember; Ε½ . 2 To exhibit a counterexample to a conjecture of Kayalar and Weinert; Ε½ . Ε½ . 3 To show that in the case of at least three

β¦ Synopsis
The convergence of the S matrix for the renormalized Numerov method, the original log-derivative method, and. one recent version of this method is studied. A single-and a two-channel problem are analyzed and the percent relative errors for the S matrix and transition probabilities are calculated.
