Abstract
Let f be a map from V(G) to . For each edge uv assign the label . f is called a mean cordial la- beling if and , , where and denote the number of vertices and edges respectively labelled with x ( ). A graph with a mean cordial labeling is called a mean cor- dial graph. We investigate mean cordial labeling behavior of Paths, Cycles, Stars, Complete graphs, Combs and some more standard graphs.
