Asymptotical invariant and asymptotical lacunary invariant equivalence types for double sequences via ideals using modulus functions
Dündar, Erdinç; Akın, Nimet Pancaroğlu; Ulusu, Uğur (Honam Mathematical Society, 2021)In this study, we present some asymptotical invariant and asymptotical lacunary invariant equivalence types for double sequences via ideals using modulus functions and investigate relationships between them. -
I-limit and I-cluster points for functions defined on amenable semigroups
Ulusu, Uğur; Nuray, Fatih; Dündar, Erdinç (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 ... -
Invariant and lacunary invariant statistical equivalence of order β for double set sequences
Ulusu, Uğur; Dündar, Erdinç; Nuray, Fatih (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 ... -
On rough convergence in amenable semigroups and some properties
Dündar, Erdinç; Ulusu, Uğur (IOS Press, 2021)The authors of the present paper, firstly, investigated relations between the notions of rough convergence and classical convergence, and studied on some properties of the rough convergence notion which the set of rough ... -
Some properties of two dimensional interval numbers
Nuray, Fatih; Ulusu, Uğur; Dündar, Erdinç (2022)In this paper, we will introduce the notion of convergence of two dimensional interval sequences and show that the set of all two dimensional interval numbers is a metric space. Also, some ordinary vector norms will be ... -
Wijsman asymptotic lacunary I_2-invariant equivalence for double set sequences
Ulusu, Uğur; Dündar, Erdinç; Akın, Nimet Pancaroğlu (Springer, 2021)In this study, for double set sequences, we present the notions of Wijsman asymptotic lacunary invariant equivalence, Wijsman asymptotic lacunary I_2-invariant equivalence and Wijsman asymptotic lacunary I*_2-invariant ... -
Wijsman lacunary I-invariant convergence of sequences of sets
Dündar, Erdinç; Akın, Nimet Pancaroğlu; Ulusu, Uğur (Springer, 2021)In this paper, we study the concepts of Wijsman lacunary I-invariant convergence (.1.), Wijsman lacu- nary I*-invariant convergence (.2.), Wijsman p-strongly lacunary invariant convergence (.3.) of sequences of sets ...
