Abstract

By (𝐴,𝐵), we denote the set of all sequences 𝜖 such that Σ𝑎𝑛𝜖𝑛 is summable 𝐵 whenever Σ𝑎𝑛 is summable 𝐴 where 𝐴 and 𝐵 are two summability methods. In this study, applying the main theorems in (Gökçe and Sarıgöl, 2018) to summability factors, we characterize the sets (|𝑁̅,𝑝𝑛,𝜃|(𝜇),|𝑁̅,𝑞𝑛|) and (|𝑁̅,𝑝𝑛,𝜃|(𝜇),|𝑁̅,𝑞𝑛,𝜓|(𝜆)). Also, in the special case, we get some well-known results.

Keywords

Abstract

𝐴 ve 𝐵 iki toplanabilme metodu olmak üzere Σ𝑎𝑛, 𝐴 toplanabilir iken Σ𝑎𝑛𝜖𝑛, 𝐵 toplanabilir olacak şekildeki bütün 𝜖 dizilerinin kümesi (𝐴,𝐵) ile gösterilir ve 𝜖 dizisine toplanabilme çarpanı adı verilir. Bu çalışmada, (Gökçe ve Sarıgöl, 2018) tarafından verilen teoremler yardımıyla (|𝑁̅,𝑝𝑛,𝜃|(𝜇),|𝑁̅,𝑞𝑛|) ve (|𝑁̅,𝑝𝑛,𝜃|(𝜇),|𝑁̅,𝑞𝑛,𝜑|(𝜆)) toplanabilme çarpanları kümeleri karakterize edilmiştir. Ayrıca özel durumlarda, bilinen bazı sonuçlar elde edilmiştir.
