Abstract :
A Total Mean Cordial labeling of a graph G = (V;E) is a function f : V (G)→{0; 1; 2} such that for each edge xy assign the label [f(x)+f(y)/2] where x; y є V (G) and │evf (i) - evf (j)│ ≤ 1, i, j є {0; 1; 2} where evf (x) denotes the total number of vertices and edges labeled with x (x = 0; 1; 2). If there exists a total mean cordial labeling on a graph G, we will call G is Total Mean Cordial. In this paper, we investigate the Total Mean Cordial labeling behavior of fan, umbrella, dumbbell, and buttery graphs.
