Rough Convergence of Double Sequence in n-Normed Spaces

Abstract

In this study, we introduced the concepts of rough convergence, rough Cauchy double sequence and the set of rough limit points of a double sequence, as well as the rough convergence criteria associated with this set in n-normed spaces. Later, we proved that this set is both closed and convex. Finally, we presented the relationships between rough convergence and rough Cauchy double sequence in n -normed spaces.
