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

In this paper the ideas of different types of convergence of a sequence of random variables in probability, namely, statistical convergence of order α in probability, strong p-Cesàro summability of order α in probability, lacunary statistical con

In the first part of the paper, following the works of Pehlivan et al. (2004), we study the set of all A-statistical cluster points of sequences in m-dimensional spaces and make certain investigations on the set of all A-statistical cluster points of

We consider the recently introduced notion of ℐ-statistical convergence (Das, Savas and Ghosal, Appl. Math. Lett., 24(9) (2011), 1509–1514, Savas and Das, Appl. Math. Lett. 24(6) (2011), 826–830) in probabilistic normed spaces and in the follow

Following the line of (Das et al., 2011, Savas and Das, 2011), we make a new approach in this paper to extend the notion of strong convergence and more general strong statistical convergence (Şençimen and Pehlivan, 2008) using ideals and introduce

Recently in Dikranjan et al. (Fund Math 249: 185–209, 2020) an uncountable Borel subgroup $$t^s_{(2^n)}({\mathbb T}) $$ (called statistically characterized subgroup) was constructed containing the Prufer group $${\mathbb Z}(2^\infty )$$ using the n

We consider an extended version of Armacost’s problem of “description of topologically torsion elements” of the circle group and describe topologically $$s$$ -torsion and topologically $$\alpha$$ -torsion elements (which form the statistically

In this article, we consider the generalized version d g f of the natural density function introduced in Bose et al. (2018) where g : N → [ 0 , ∞ ) satisfies g ( n ) → ∞ and n g ( n ) ↛ 0 whereas f is an unbounded modulus function and gener

This article is a continuation of the study of bornological open covers and related selection principles in metric spaces done in (Chandra et al. 2020 [6]) using the idea of strong uniform converge...
