Abstract :

The notion of $I$-statistical convergence of a double sequence was first introduced by Belen et. al.cite{Be} and the notion of rough convergence of a sequence was first introduced by Phu cite{Ph}.
In this paper we introduce and study the notion of rough $I$-statistical convergence of double sequences in normed linear spaces. We also introduce the notion of rough $I$-statistical limit set of a double sequence and discuss about some topological properties of this set.

Keywords :

Double sequence, $I$-statistical convergence, rough $I$-statistical convergence,  rough $I$-statistical limit set, $I$- statistical boundedness.
