Extending tests for convergence of number series

open access: yesJournal of Mathematical Analysis and Applications, 2011
Analyzing several classical tests for convergence/divergence of number series, we relax the monotonicity assumption for the sequence of terms of the series.

Maximal sets of convergence and unbounded divergence of multiple fourier series with J κ -lacunary sequence of partial sums

Mathematical Notes, 2009
The authors characterize the structure and geometry of maximal sets of unbounded divergence and maximal sets of convergence almost everywhere of multiple Fourier series with a \(J_{k}\)-lacunary sequence of rectangular partial sums \(S_{n^{\left( \alpha \right) }\left[ J_{k}\right] }\left( x;f\right) \) for functions \(f\in L_{p}\left( T^{N}\right)\), \

On the derivation of iterated sequence transformations for the acceleration of convergence and the summation of divergent series

Computer Physics Communications, 1991
Abstract Simple explicit expressions for named sequence transformations such as Wynn's ρ algorithm (Proc. Cambridge Philos. Soc. 52 (1956) 663) and Drummond's sequence transformation (Bull. Aust. Math. Soc. 6 (1972) 69), which is used in connection with remainder estimates introduced by Levin (Int. J. Comput. Math.

An introduction to the topics presented at the conference “Approximation and extrapolation of convergent and divergent sequences and series” CIRM Luminy: September 28, 2009–October 2, 2009

Applied Numerical Mathematics, 2010
The conference ''Approximation and extrapolation of convergent and divergent sequences and series'' discusses some very old problems of mathematical analysis and modern approaches for their solution based on so-called nonlinear sequence transformations. In spite of all the advances in computer hard and software, slowly convergent or divergent sequences
