Acceleration by subsequence transformations
Thomas A. Keagy, William F. Ford · Pacific Journal of Mathematics · 1988
The acceleration field of subsequence matrix transformations are studied with respect to the convergence rate of the sequence being accelerated.Included is a proof that no subsequencing algorithm exists which will determine a set of subscripts (/?(/)) for which (y Π (,)) will be linear for every y which converges at the same rate as or faster (slower) than a fixed sequence Λ\
