Dominating Critical in Intuitionistic Fuzzy Graphs

Abstract

Let G be an IFG. Then V D  is said to bae a strong (weak)is strongly (weakly) dominated by some vertex in D. We denote the strong (weak) intuitionistic fuzzy dominating set by sid-set (wid-set). The minimum vertex cardinality over all the sid-set (wid-set) is called the strong (weak) dominating number of an IFG and isIn this paper, we introduce the strong (weak) domination in intuitionistic fuzzy graphs and obtain some bounds in IFG.
