Lacunary statistical convergence of double sequences of sets
Nuray, Fatih; Ulusu, Uğur; Dündar, Erdinç (2016)In this paper, we study the concepts of Wijsman statistical convergence, Wijsman lacunary statistical convergence, Wijsman lacunary convergence and Wijsman strongly lacunary convergence double sequences of sets and investigate ... -
Lacunary statistical convergence of sequences of sets
Ulusu, Uğur; Nuray, Fatih (Canadian Research & Development Center of Sciences and Cultures, 2012)Several notions of convergence for subsets of metric space appear in the literature. In this paper we define lacunary statistical convergence for sequences of sets and study in detail the relationship between other convergence ... -
Lacunary statistical summability of sequences of sets
Ulusu, Uğur; Nuray, Fatih (Konuralp Journal of Mathematics, 2015)In this paper we define the WS_θ-analog of the Cauchy criterion for convergence and show that it is equivalent to Wijsman lacunary statistical convergence. Also, Wijsman lacunary statistical convergence is compared to other ... -
On almost asymptotically lacunary statistical equivalence of sequences of sets
Ulusu, Uğur (Fractional Calculus and Application Group, 2014)In this paper we study the concepts of Wijsman almost asymptotically statistical equivalent, Wijsman almost asymptotically lacunary statistical equivalent and Wijsman strongly almost asymptotically lacunary equivalent sequences ... -
On asymptotically lacunary statistical equivalent set sequences
Ulusu, Uğur; Nuray, Fatih (Hindawi Publishing Corporation, 2013)This paper presents three definitions which are natural combination of the definitions of asymptotic equivalence, statistical convergence, lacunary statistical convergence, and Wijsman convergence. In addition, we also ... -
On ideal invariant convergence of double sequences and some properties
Dündar, Erdinç; Ulusu, Uğur; Nuray, Fatih (Creative Mathematics and Informatics, 2018)In this paper, we study the concepts of invariant convergence, p-strongly invariant convergence ([V_2σ ]p), I2-invariant convergence (I^σ_2), I∗_2-invariant convergence (I^σ∗_2) of double sequences and investigate the ... -

On strongly lacunary summability of sequences of sets
Ulusu, Uğur; Nuray, Fatih (Journal of Applied Mathematics & Bioinformatics, 2013)In this paper, we introduce the concept of Wijsman strongly lacunary summability for set sequences. Then, we discus its relation with Wijsman strongly Ces`aro summability. Furthermore, we also give its relation with Wijsman ... -
Quasi-almost convergence of sequences of sets
Gülle, Esra; Ulusu, Uğur (Ilirias Publications, 2017)In this paper, we defined concepts of Wijsman quasi-almost convergence and Wijsman quasi-almost statistically convergence. Also we give the concepts of Wijsman quasi-strongly almost convergence and Wijsman quasi q-strongly ... -
