In this paper, the duplication of an arbitrary vertex by a new edge of cycle C n (n  3), the duplication of an arbitrary edge by a new vertex of cycle C n (n  3),   (3) n a path P k (n  4).

In this paper, we introduce the various types of neighbourhood cordial labeling of graphs and present the neighbourhood cordial labeling of kP 2 ,

In this paper, we investigate the face edge product cordial labeling of the alternative triangular snakes, K 1,n P m and (P n K 1)P m. Also non face edge product cordial labeling of the graph DS(P n) is presented.

Let G be an IFG. Then V D  is said to be a strong (weak)is strongly (weakly) dominated by some vertex in D. We denote the strong (weak) intunionistic 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 is denoted by.In this paper, introduce the strong (weak) domination in intunionistic fuzzy graphs and obtain some bounds in IFG.

In this paper we discuss several operations on intuitionistic fuzzy graph such as union, join, composition, Cartesian product and study their domination parameters.
