Odd Fibonacci edge irregular labelling for some simple graphs
Main Article Content
Abstract
Let G be a graph with p vertices and q edges and be an injective function, where k is a positive integer. If the induced edge labeling defined by f*(uv) = f(u)+f(v), for each , is a bijection, then the labeling f is called an odd Fibonacci edge irregular labeling of G. A graph which admits an odd Fibonacci edge irregular labeling is called an odd Fibonacci edge irregular graph. The odd Fibonacci edge irregularity strength ofes(G) is the minimum k for which G admits an odd Fibonacci edge irregular labeling. The odd Fibonacci edge irregularity strength for Pn , K1,n , PnʘK1, B(m,n) and the non existence of an odd Fibonacci edge irregular labeling for the graphs Kp , Km,n have been determined.
