Summable Series and Convergence Factors
, 1938 Fairly early in the development of the theory of summability of divergent series, the concept of convergence factors was recognized as of fundamental importance in the subject. One of the pioneers in this field was C. N.

On Linear Functionals and Summability Factors for Strong Summability II
, 1981 The first part of this paper, which will be referred to by I, appeared in Volume 30 of this journal. The present paper will use the same bibliography as I.Theorem 1 in I shows that the knowledge of all continuous linear functionals in o[A]p is essential ...

Determination of jumps via advanced concentration factors
, 2009 If a periodic function f with period 2π has a discontinuity at ξ∈[−π,π), then the partial sums of its Fourier conjugate series diverge to + or − infinity at ξ. It was shown in [F.

Integrability and $L^1$-convergence of Rees-Stanojević sums with generalized semi-convex coefficients of non-integral orders [PDF]
, 2005 summary:Integrability and $L^{1}-$convergence of modified cosine sums introduced by Rees and Stanojević under a class of generalized semi-convex null coefficients are studied by using Cesàro means of non-integral ...
