On Absolute Cesàro Summability

A note on generalized absolute Cesàro summability

In this paper, a known theorem dealing with | C, 1 |k summability methods has been generalized under weaker conditions for | C, α, β ; δ |k summability methods. Some new results have also been obtained. AMS subject classifications: 40D15, 40F05, 40G99

On Generalized Absolute Cesàro Summablity Factors

In this paper, we prove a known theorem dealing with φ− | C, α, β |k summability factors under more weaker conditions. This theorem also includes several new results.

A One-sided Theorem for the Product of Abel and Cesàro Summability Methods

In this paper, a one-sided condition is given to recover .C; ̨/ summability of a sequence from its .A/.C; ̨C 1/ summability. Our result extends and generalizes the well known classical Tauberian theorems given for Abel and Cesàro summability methods. 2010 Mathematics Subject Classification: 40E05; 40G05; 40G10

Cesàro Summability of Double Sequences of Sets

In this paper, we study the concepts of Wijsman Cesàro summability and Wijsman lacunary convergence of double sequences of sets and investigate the relationship between them.
