Fibonacci divisor cordial graphs

Let $G=(V,E)$ be a $(p,q)$-graph. A Fibonacci divisor cordial labeling of a graph G with vertex setV is a bijection $f : V ightarrow {F_1, F_2,F_3,dots ,F_p}$, where$F_i$ is the $i^{th}$ Fibonacci number such that if each edge $uv$ is assigned the label $1$ if $f(u)$ divides $f(v)$ or $f(v)$ divides $f(u)$ and $0$ otherwise, then the number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. If a graph has a Fibonacci divisor cordial labeling, then it is called Fibonacci divisor cordial graph. In this paper, we prove that the graphs $P_n$, $C_n$, $K_{2,n} odot u_2(K_1)$ and subdivision of bistar( extless $B_ {n,n}:w>)$ are Fibonacci divisor cordial graphs. We also prove that $K_n(ngeq 3)$ is not Fibonacci divisor cordialgraph.
