چکیده:

Let ? = (?,?) be a fuzzy graph. Then S? ? is said to be a restrained dominating set of , if where every vertex in dominates a vertex in ? as well as another vertex in . The minimum fuzzy cardinality of such a set is called the restrained domination number of and denoted by . In this paper we study restrained dominating set and global restrained dominating set in a graph and investigate the relationship other known parameters of
