Invariant summability and invariant statistical convergence of order η for double set sequences
(2021)
In this study, for double set sequences, we introduce the notions of invariant summability and invariant statistical convergence of order η (0 < η ≤ 1) in the Wijsman sense. Also, we investigate some properties of these ...
I-convergent functions defined on amenable semigroups
(2020)
In this paper, we introduce and study the concepts of I-convergence, I*-convergence, I-Cauchy sequence and I*-Cauchy sequence of functions defined on discrete countable
amenable groups, where I is an ideal of subsets of ...
