FP-cordial labeling of product and corona related graphs

Let Formula: see text be a Formula: see text graph. Let Formula: see text Let Formula: see text be a bijection.For each edge Formula: see text assign the label Formula: see text.Formula: see text is called a fractional product cordial labeling (simply called FP-cordial labeling) if Formula: see text where Formula: see text and Formula: see text respectively denotes the number of edges labelled with Formula: see text and not labelled with Formula: see text. A graph with a fractional product cordial labeling is called a fractional product cordial graph (Simply FP-cordial graph).In this paper we investigate the fractional product cordial labeling behaviour of planar grid graph, Formula: see text, mangolian tent graph, double arrow graph, Formula: see text, Formula: see text, Formula: see text, Formula: see text and Formula: see text.
