Some properties of 2-dimensional interval numbers
Nuray, Fatih; Dündar, Erdinç; Ulusu, Uğur (International Conference on Mathematical and Related Sciences, 2018)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 ... -
Some uniform continuity definitions for real valued functions and some properties
Nuray, Fatih; Ulusu, Uğur; Dündar, Erdinç (International Conference on Advances in Natural and Applied Sciences, 2017)The purpose of this study is to give some uniform continuity definitions for real valued functions and investigate some properties about these concepts. -
Statistical lacunary invariant summability of double sequences
Ulusu, Uğur; Gülle, Esra (2018)In this study, we give definitions of lacunary σ-summability, strongly p-lacunary σ-summability and statistical lacunary σ-convergence for double sequences. We also examine the existence of some relations among the definitions ... -

Wijsman and Hausdorff statistical convergence of order α for double set sequences
Ulusu, Uğur; Gülle, Esra (3rd International Congress on Science and Education, 2019)The concept of statistical convergence was introduced by Steinhaus (1951) and Fast (1951), and later reintroduced by Schoenberg (1959) independently. Then, many researchers have studied on this concept until recently (see ... -
