Ideal convergent subseries in Banach spaces [PDF]
Assume that $\mathcal{I}$ is an ideal on $\mathbb{N}$, and $\sum_n x_n$ is a divergent series in a Banach space $X$. We study the Baire category, and the measure of the set $A(\mathcal{I}):=\left\{t \in \{0,1\}^{\mathbb{N}} \colon \sum_n t(n)x_n \textrm{ is } \mathcal{I}\textrm{-convergent}\right\}$.

Double sequences with ideal convergence in fuzzy metric spaces [PDF]
We show ideal convergence (I-convergence), ideal Cauchy (I-Cauchy) sequences, I* -convergence and I*-Cauchy sequences for double sequences in fuzzy metric spaces. We define the I-limit and I-cluster points of a double sequence in these spaces. Afterward,

On ideal convergence Fibonacci difference sequence spaces
The Fibonacci sequence was firstly used in the theory of sequence spaces by Kara and Başarir (Casp. J. Math. Sci. 1(1):43–47, 2012). Afterward, Kara (J. Inequal. Appl.

On $A$-statistical convergence and $A$-statistical Cauchy via ideal
In [Analysis 1985, 5 (4), 301-313], J.A. Fridy proved an equivalence relation between statistical convergence and statistical Cauchy sequence. In this paper, we define $A^{I^{\ast }}$-statistical convergence and find under certain conditions, that it is ...

Convergence in trace ideals [PDF]
We give an elementary proof of a theorem of Arazy which presents necessary and sufficient conditions on a symmetric sequence so that the associated symmetrically normed trace ideal has the property that if

An alternative approach to ideal Wijsman convergence
Summary: The concept of Wijsman convergence of a sequence of sets was defined using the pointwise convergence of the sequence of distance functions. Based on this idea, in this article, a new type of set convergence is obtained by using the concept of ideal \(\alpha\)-convergence for the sequence of distance functions.

A Study on(λ−µ)Zweier Sequences and Their Behaviour in Neutrosophic Normed Spaces [PDF]
Ideal convergence of sequences in neutrosophic normed spaces is defined by ¨Omer Ki¸si [12]. This paper defines new sequence spaces using the Zweier matrix and neutrosophic norm.

On Generalized Difference Rough Ideal Statistical Convergence in Neutrosophic Normed Spaces [PDF]
This article’s main goal is to provide and investigate a novel statistical convergence generalisation for generalized difference sequences in Neutrosophic Normed Spaces (NNS) called rough ideal statistical convergence.

Ideal Convergence in neutrosophic 2-normed space via the parameter µ and Zweier Operator [PDF]
This paper introduces a novel convergence concept termed μ− Zweier ideal convergence within neutrosophic 2-normed spaces (briefly, N2NS). The parameter μ = (μn) represents a non-decreasing sequence of positive real numbers, with each μn tending to ...

The authors use ideal convergence (\(\mathcal I\)-convergence), where \(\mathcal I\) is a \(D\)-admissible proper ideal on a directed set \(D\), to define \(\mathcal I\)-convergence classes. Several results in this context are obtained. In the main result of the paper (Theorem 4.3) it is shown how \(\mathcal I\)-convergence classes on a set \(X ...
