چکیده
In this article we introduce and study the notions of ∆(r)-lacunary strongly summable, ∆(r)-Cesàro strongly summable, ∆(r)-statistically convergent and ∆(r)-lacunary statistically convergent sequences of fuzzy numbers. Consequently we construct the spaces of these four types of difference sequences and investigate the relationship among these spaces. Further we show that the spaces of ∆(r)-lacunary strongly summable and ∆(r)-Cesàro strongly summable sequences are complete metric spaces.

In this article we introduce and study the notions of double -lacunary strongly summable, double Cesàro strongly summable, double statistically convergent and double -lacunary statistically convergent sequence of fuzzy numbers. Consequently we construct the spaces 2 F L , 2 F , 2 F S and 2 F S respectively and investigate the relationship among these spaces. F...
متن کاملA Tauberian theorem for $(C,1,1)$ summable double sequences of fuzzy numbers
In this paper, we determine necessary and sufficient Tauberian conditions under which convergence in Pringsheim's sense of a double sequence of fuzzy numbers follows from its $(C,1,1)$ summability. These conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. We also construct some interesting double sequences of fuzzy numbers.
متن کامل(A, p)-summable sequences of fuzzy numbers
We introduce the the classes of strongly V F λ (A, p)-summable sequences of fuzzy numbers and give some relations between these classes. We also give a natural relationship between strongly V F λ (A, p)convergence of sequences of fuzzy numbers and strongly S λ (A)-statistical convergence of sequences of fuzzy numbers.
متن کاملSome topological properties of fuzzy strong b-metric spaces
In this study, we investigate topological properties of fuzzy strong b-metric spaces defined in [13]. Firstly, we prove Baire's theorem for these spaces. Then we define the product of two fuzzy strong b-metric spaces defined with same continuous t-norms and show that $X_{1}times X_{2}$ is a complete fuzzy strong b-metric space if and only if $X_{1}$ and $X_{2}$ are complete fu...
