DOMINATION IN FUZZY GRAPH
In this paper, we define domination in fuzzy graph using strong arcs. Let
be a fuzzy graph with node set V. Let u and v be any two nodes of G. We say that u dominates v if
is a strong arc. A subset D of V is called a dominating set of G if for every
there exists
such that u dominates v. A dominating set D is called a minimal dominating set if no proper subset of D is a dominating set. The smallest number of nodes in any dominating set of
is called its domination number and is denoted by
We discuss some properties of dominating set and find domination number for some standard graphs. We also give some bounds for
fuzzy graph, strong arcs, fuzzy independent set, dominating set, domination number.
