In his classical paper [14], Rosa introduced a hierarchical series of labelings called ρ, σ, β and α labeling as a tool to settle Ringel’s Conjecture which states that if T is any tree with m edges then the complete graph K2m+1 can be decomposed into 2m +

Gaussian Tribonacci R-Graceful Labeling of Some Tree Related Graphs
Let r be any natural number. An injective function , where is the Gaussian Tribonacci number in the Gaussian Tribonacci sequence is said to be Gaussian Tribonacci r-graceful labeling if the induced edge labeling such that is bijective.

It is well known that the labeling problems of graphs arise in many (but not limited to) networking and telecommunication contexts. In this paper we introduce the anti-$k$-labeling problem of graphs which we seek to minimize the similarity (or distance) of neighboring nodes.

A $k$-dispersed labelling of a graph $G$ on $n$ vertices is a labelling of the vertices of $G$ by the integers $1, \dots , n$ such that $d(i,i+1) \geq k$ for $1 \leq i \leq n-1$. $DL(G)$ denotes the maximum value of $k$ such that $G$ has a $k$-dispersed labelling. In this paper, we study upper and lower bounds on $DL(G)$.

PMC-LABELING OF SOME CLASSES OF GRAPHS CONTAINING CYCLES
Let be a graph with p vertices and q edges. We have introduced a new graph labeling method using integers and cordial-related works and investigated some graphs for this labeling technique.

Neutrosophic Divisor Cordial Labeling Graphs [PDF]
In this paper we introduced a novel concept – Neutrosophic Divisor Cordial Labeling a have proved that graphs such as wheels, helms and closed helm graph satisfy this new labeling. This paper builds upon our previous work in Neutrosophic Cordial Labeling

On Integer Cordial Labeling of Some Families of Graphs
An integer cordial labeling of a graph $G(p,q)$ is an injective map $f:V\rightarrow [-\frac{p}{2}...\frac{p}{2}]^*$ or $[-\lfloor{\frac{p}{2}\rfloor}...\lfloor{\frac{p}{2}\rfloor}]$ as $p$ is even or odd, which induces an edge labeling $f^*: E ...

On Square Sum Labeling of Two Families of Petersen Graphs
A labeling on a graph G with n vertices and m edges is called square sum if there exists a bijection f:VG⟶0,1,2,3,…,n−1 such that the function f∗:EG⟶N defined by f∗st=fs2+ft2, for all st∈EG, is injective.

This paper deals with so-called \(d\)-Skolem labelled graphs and \(d\)-hooked Skolem labelled graphs. After quoting and representing main results in terms of \(d\)-Skolem labelled graphs the authors prove a lot of new theorems. Most of them give new classes of \(d\)-Skolem labelled graphs.

Note on edge irregular reflexive labelings of graphs
For a graph , an edge labeling and a vertex labeling are called total -labeling, where . The total -labeling is called an edge irregular reflexive -labeling of the graph , if for every two different edges and of , one has The minimum for which the graph ...
