Title: A new proof of global convergence for the tridiagonal QL
Author: Hoffmann, Walter

Abstract: By exploiting the relation of the QL algorithm to inverse
iteration we obtain a proof of global convergence which is
more conceptual and less computational than previous
analyses. The proof uses a new, but simple, error estimate
for the first step of inverse iteration.
