3-total edge product cordial labeling of rhombic grid

Abstract

For a simple graph , this paper deals with the existence of an edge labeling , which induces a vertex labeling in such a way that for each vertex , assigns the label where are the edges incident to the vertex . The labeling is called a -total edge product cordial labeling of if for every , where and are the number of edges and vertices with and , respectively. In this paper, we examine the existence of such labeling for rhombic grid graph.
