On Rough I2-Convergence of Double Sequences

Abstract

In this study, we introduce the notion of rough I-2-convergence and the set of rough I-2-limit points of a double sequence and obtained two rough I-2-convergence criteria associated with this set. Later, we proved that this set is closed and convex. Finally, we examined the relationships between the set of cluster points and the set of rough I-2-limit points of a double sequence.
