• #### E-core of double sequences ﻿

Boos, Leiger and Zeller [1,2] deﬁned the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for real double sequences and prove some fundamental properties of e-limit ...
• #### I-limit superior and I-limit inferior for sequences of fuzzy numbers ﻿

The statistical limit inferior and limit superior for sequences of fuzzy numbers have been introduced by Aytar, Pehlivan and Mammadov (Fuzzy Sets and Systems, 157(7) (2006) 976{985). In this paper we extend concepts of ...
• #### I_2-Cauchy double sequences of fuzzy numbers ﻿

In this paper, we introduce the concepts of I2-Cauchy, I∗2-Cauchy double sequence of fuzzy numbers and study their some properties and relations, where I2 denotes the ideal of subsets of N × N.
• #### I_2-Convergence of double sequence of fuzzy numbers ﻿

In this paper, we introduce and study the concepts of I_2-convergence, I∗_2-convergence for double sequences of fuzzy real numbers, where I_2 denotesthe ideal of subsets of N × N. Also, we study some properties and relations ...
• #### On Kuratowski i-convergence of sequences of closed sets ﻿

(JSTOR, 2017)
In this paper we extend the concepts of statistical inner and outer limits (as introduced by Talo, Sever and Bas¸ar) to I− inner and I− outer limits and give some I− analogue of properties of statistical inner and outer ...
• #### On statistical convergence of double sequences of closed sets ﻿

(JSTOR, 2016)
In this paper, we introduce the concepts of statistical inner and statistical outer limits for double sequences of closed sets and give some formulas for ﬁnding these limits. Also, we give the Kuratowski statistical ...
• #### On statistically convergent sequences of closed sets ﻿

In this paper, we give the definitions of statistical inner and outer limits for sequences of closed sets in metric spaces. We investigate some properties of statistical inner and outer limits. For sequences of closed ...
• #### Regularly (I_2, I)-convergence and regularly (I_2, I)-Cauchy double sequences of fuzzy numbers ﻿

In this paper, we introduce the notions of regularly, (I_2,I)-convergence and regularly, (I_2,I)-Cauchy double sequence of fuzzy numbers. Also, we study some properties of these concepts.
