ROUGH I-CONVERGENCE OF SEQUENCES IN 2-NORMED SPACES.

In this paper, we have introduced the notions of rough I-convergence of sequences and defined I-cluster point of a sequence and proved some results associated with this notion in 2-normed spaces. Also, we have defined rough I-limit set of a sequence and shown that this set is closed and convex. Further, we have defined the notion of rough I-Cauchy sequence in the same space.
