Some Results on Cesàro summability in Intuitionistic Fuzzy $n$-normed linear Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
The concept of summability plays a central role in finding formal solutions of partial differential equations. In this paper, we introduce the concept of Cesàro summability in an intuitionistic fuzzy $n$-normed linear space (IFnNLS).

On the Euler method of summability and concerning Tauberian theorems

open access: yesCumhuriyet Science Journal, 2021
For any two regular summability methods (U) and (V), the condition under which V-limx_n=λ implies U-limx_n=λ is called a Tauberian condition and the corresponding theorem is called a Tauberian theorem.

Tauberian theorems for weighted means of double sequences in intuitionistic fuzzy normed spaces [PDF]

open access: yesYugoslav Journal of Operations Research, 2022
We define weighted mean summability method of double sequences in intuitionistic fuzzy normed spaces(IFNS), and obtain necessary and sufficient Tauberian conditions under which convergence of double sequences in IFNS follows from their weighted mean ...

New Observation on Cesaro Summability in Neutrosophic -Normed Linear Spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
We define Cesaro summability in a Neutrosophic 𝓃 -Normed Linear Space in this article. In a Neutrosophic 𝓃-Normed Linear Space, we show the Cesaro summability method to be regular, albeit this does not imply typical convergence in general.

A new extension on the theorem of Bor

open access: yesComptes Rendus. Mathématique, 2021
In [8], Bor has obtained a main theorem dealing with Riesz summability factors of infinite series and Fourier series. In this paper, we generalized that theorem to $|A,\theta _{n}|_{k}$ summability method for taking power increasing sequence.

Ideals, Nonnegative Summability Matrices and Corresponding Convergence Notions: A Short Survey of Recent Advancements

open access: yesAxioms, 2021
In this survey article, we look into some recent results concerning summability matrices, both regular as well as those which are not regular (called semi-regular) and generated matrix ideals as the overall view of the inter relationship between the ...
