Some more Extensions on Product Cordial Graphs

Abstract

A mapping function , causes an labeling of edge  as specified  by   . This type of labeling is called product cordial labeling if it satisfies certain circumstances regarding the differences in the number of vertices and edges labeled with 0 and 1. In this investigation, we prove that the copies of concentric n-sunlet graphs, star of concentric n-sunlet graph and copies of shell graph satisfies these conditions, eventually they are product cordial graphs.
