On some double sequence spaces of interval number
Abstract Esi and Yasemin defined the metric spaces , , l∞(f, p, s) and of sequences of interval numbers by a modulus function. In this study, we consider a generalization for double sequences of these metric spaces by taking a ψ function, satisfying the following conditions, i...

| Sumario: | Abstract Esi and Yasemin defined the metric spaces , , l∞(f, p, s) and of sequences of interval numbers by a modulus function. In this study, we consider a generalization for double sequences of these metric spaces by taking a ψ function, satisfying the following conditions, instead of s parameter. For this aim, let ψ(k, l) be a positive function for all k, l ∈ N such that or ψ(k, l) = 1. Therefore, according to class of functions which satisfying the conditions (i) and (ii) we deal with the metric spaces and of double sequences of interval numbers defined by a modulus function. |
