Abstract :
In this paper, we shall introduce lower and upper approximation operators of rough sets are applied into topological group theory and so the notion of a topo- logical rough subgroup has been introduced. Then, we present some propositions and continue to study the image and inverse image of rough approximations of a subgroup with respect to a continuous homomorphism between two topological groups.
