Invariant and lacunary invariant statistical equivalence of order β for double set sequences
(Adıyaman Üniversitesi, 2021)
In this study, as a new approach to the concept of asymptotical equivalence in the Wijsman sense for double set sequences, the new concepts which are called asymptotical invariant statistical equivalence of order β and ...
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-limit and I-cluster points for functions defined on amenable semigroups
(2021)
In this paper firstly, for functions defined on discrete countable amenable semigroups
(DCASG), the notions of I-limit and I-cluster points are introduced. Then, for the functions,
the notions of I-limit superior and ...
