A bounded consistency theorem for strong summabilities [PDF]
International Journal of Mathematics and Mathematical Sciences, 1989 The study of R-type summability methods is continued in this paper by showing that two such methods are identical on the bounded portion of the strong summability field associated with the methods.

Matrix Transformations between Certain Sequence Spaces over the Non-Newtonian Complex Field [PDF]
The Scientific World Journal, 2014 In some cases, the most general linear operator between two sequence spaces is given by an infinite matrix. So the theory of matrix transformations has always been of great interest in the study of sequence spaces. In the present paper, we introduce the

On absolute factorable matrix summability methods [PDF]
, 2016 Summary: In this paper, we give necessary and sufficient conditions for \(| C, 0|_k\Rightarrow | A_f|_s\) and \(| A_f|_k\Rightarrow | C, 0|_s\) for the case \(1 < k \leq s < \infty\), where \(| A_f|_k\) is absolute factorable summability. So we obtain some known results.

F-seminorms on generalized double sequence spaces defined by modulus functions; pp. 121–132 [PDF]
Proceedings of the Estonian Academy of Sciences, 2014 Using a double sequence of modulus functions and a solid double scalar sequence space, we determine F-seminorm and F-norm topologies for certain generalized linear spaces of double sequences.

Multiplicative Summability Methods and the Stone-Čech Compacification [PDF]
, 1959 A regular summability method ψ (for real sequences) is called multiplicative (b-multiplicative) if whenever f, g are two (bounded) sequences summed by ψ, then ψ(fg) = ψ(f)ψ(g). It is known [11], [17], p.
