Some Tauberian theorems for four-dimensional Euler and Borel summability
The four-dimensional summability methods of Euler and Borel are studied as mappings from absolutely convergent double sequences into themselves. Also some Tauberian results are proved.
On some properties of I_2-Convergence and I_2-Cauchy of double sequences
In this paper we study the concepts of I-Cauchy and I∗-Cauchy for double sequences in a linear metric space. Also, we give the relation between I-convergence and I*-convergence of double sequences of functions defined ...
Regularly (I_2, I)-convergence and regularly (I_2, I)-Cauchy double sequences of fuzzy numbers
In this paper, we introduce the notions of regularly, (I_2,I)-convergence and regularly, (I_2,I)-Cauchy double sequence of fuzzy numbers. Also, we study some properties of these concepts.
I_2-Cauchy double sequences of fuzzy numbers
In this paper, we introduce the concepts of I2-Cauchy, I∗2-Cauchy double sequence of fuzzy numbers and study their some properties and relations, where I2 denotes the ideal of subsets of N × N.
On rough I_2-convergence of double sequences
(Numerical Functional Analysis and Optimization, 2016)
In this study, we introduce the notion of rough ℐ_2-convergence and the set of rough ℐ_2-limit points of a double sequence and obtained two rough ℐ_2-convergence criteria associated with this set. Later, we proved that ...
A characterization of holomorphic bivariate functions of bounded index
The following notion of bounded index for complex entire functions was presented by Lepson. function f(z) is of bounded index if there exists an integer N independent of z, such that The main goal of this paper is extend ...
Inclusion theorems of double Deferred Cesàro means II
In 1932 R. P. Agnew present a definition for Deferred Ces`aro mean. Using this definition R. P. Agnew present inclusion theorems for the deferred and none Deferred Ces`aro means. This paper is part 2 of a series of papers ...
Multipliers for bounded I_2-convergence of double sequences
Multipliers and factorizations for bounded statistically convergent sequences were studied by Connor et al. [J. Connor, K. Demirci, C. Orhan, Multipliers and factorizations for bounded statistically convergent sequences, ...
Asymptotically lacunary I 2 -invariant equivalence
(IOS Press, 2019)
In this paper, the concept of asymptotically lacunary I_2-invariant equivalence, the concepts of asymptotically lacunary σ_2-equivalence and the concept of asymptotically lacunary invariant S_2-equivalence for double ...
I_2-Convergence of double sequence of fuzzy numbers
In this paper, we introduce and study the concepts of I_2-convergence, I∗_2-convergence for double sequences of fuzzy real numbers, where I_2 denotesthe ideal of subsets of N × N. Also, we study some properties and relations ...
