Convergence theorems for intermediate problems. II
Christopher Beattie, W. M. Greenlee · Proceedings of the Royal Society of Edinburgh Section A Mathematics · 2002
Convergence theorems for the practical eigenvector free methods of Gay and Goerisch are obtained under a variety of hypotheses, so that our theorems apply to both traditional boundary-value problems and atomic problems. In addition, we prove convergence of the T * T method of Bazley and Fox without an alignment of projections hypothesis required in previous literature.
