ROUGH CONVERGENCE OF DOUBLE SEQUENCES OF FUZZY NUMBERS

Journal of Applied Analysis and Computation, 2020
Summary: In this paper, we define the concepts of rough convergence and rough Cauchy sequence of double sequences of fuzzy numbers. Then, we investigate some relations between rough limit set and extreme limit points of such sequences.

Rough statistically convergent double sequences

AIP Conference Proceedings, 2012
In this paper, we define the concepts of rough statistical convergence and rough statistical Cauchy of a double sequence. Then we obtain a rough statistically Cauchy criterion for the real double sequences.

On Convergence of Rough Sets

1992
Various considerations of analysis of knowledge by means of rough sets lead to the following situation: we are given a universe U along with a descending sequence of equivalence relations. We propose metrics for rough sets that make them into a complete metric space; the metric convergence encompasses and generalizes approximative convergence studied ...

ROUGH IDEAL CONVERGENCE

2014
In this paper we extend the notion of rough convergence using theconcept of ideals which automatically extends the earlier notions ofrough convergence and rough statistical convergence. We define the setof rough ideal limit points and prove several results associated with thisset.

Rough statistical convergence for generalized difference sequences

2023
Summary: In this work, we introduce the rough statistical convergence for normed linear spaces with generalized difference sequences. We also define the set of \(r\)-statistical limit points for generalized difference sequences and discuss some topological properties of this set.

Statistical Convergence of Rough Variable

2021
In this paper, we present the concept of statisticallyconvergent sequences for rough variables. Furthermore, the relation between convergence statistically in trust and converges $\lambda$-statistically in trust is given. Also, some properties of statistically convergent sequences are discussed.

ROUGH ?I-STATISTICAL CONVERGENCE

In this study, we examine rough.I-statistical convergence for difference sequences as an extension of rough convergence. We investigate the set of rough Delta I-statistical limit points of a difference sequence and analyze the results with proofs.
