Ingham Tauberian theorem with an estimate for the error term

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 64, Page 4025-4031, 2003., 2003
We estimate the error term in the Ingham Tauberian theorem. This estimation of the error term is accomplished by considering an elementary proof of a weak form of Wiener′s general Tauberian theorem and by using a zero‐free region for the Riemann zeta function.

Necessary and sufficient conditions under which convergence follows from summability by weighted means

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 7, Page 399-406, 2001., 2001
We prove necessary and sufficient Tauberian conditions for sequences summable by weighted mean methods. The main results of this paper apply to all weighted mean methods and unify the results known in the literature for particular methods. Among others, the conditions in our theorems are easy consequences of the slowly decreasing condition for real ...

Tauberian conditions for Conull spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 8, Issue 4, Page 689-692, 1985., 1985
The typical Tauberian theorem asserts that a particular summability method cannot map any divergent member of a given set of sequences into a convergent sequence. These sets of sequences are typically defined by an “order growth” or “gap” condition. We establish that any conull space contains a bounded divergent member of such a set; hence, such sets ...

Some Tauberian theorems for Euler and Borel summability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 3, Issue 4, Page 731-738, 1980., 1979
The well‐known summability methods of Euler and Borel are studied as mappings from ℓ1 into ℓ1. In this ℓ − ℓ setting, the following Tauberian results are proved: if x is a sequence that is mapped into ℓ1 by the Euler‐Knopp method Er with r > 0 (or the Borel matrix method) and x satisfies , then x itself is in ℓ1.
