The Order of Accuracy for Deferred Corrections Using Uncentered End Formulas
Robert D. Skeel · SIAM Journal on Numerical Analysis · 1986
A result of Christiansen and Russell [SIAM J. Numer. Math., 35 (1980), pp. 21–33] on the order of accuracy of an iterated deferred corrections algorithm of Lentini and Pereyra [SIAM J. Numer. Math., 14 (1977), pp. 91–111] is improved, at the same time providing a realistic example for a theoretical framework developed by the author for proving accuracy results for deferred corrections.
