Decomposition of Certain Complete Graphs and Complete Multipartite Graphs into Almost-bipartite Graphs and Bipartite Graphs

open access: yesTheory and Applications of Graphs, 2020
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 +

Fibonacci and Super Fibonacci Graceful Labeling of Some Graphs [PDF]

open access: yes, 2011
In the present work we discuss the existence and non-existence of Fibonacci and super Fibonacci graceful labeling for certain graphs. We also show that the graph obtained by switching a vertex in cycle Cn, (where 6n ) is not super Fibonacci graceful but

BEBERAPA ALGORITMA PELABELAN GRACEFUL UNTUK GRAF CATERPILLAR [PDF]

open access: yes, 2023
Graceful labeling, first introduced by Rosa as β-labeling. A graceful labeling (or β-labeling) on a graph G involves assigning labels to its set of vertices, forming an injective function f that maps each vertex to the set of non-negative integers {0 ...

SUPER EDGE MAGIC GRACEFUL TOTAL LABELING OF SOME GRAPHS [PDF]

open access: yes, 2019
Let a ( , ) p q graph G with the vertex set V G( ) , the edge set E G( ) , the number of vertices is p, and the number of edges is q. The edge magic graceful total labeling of graph G is a bijection from V G E G ( ) ( ) to the integers {1, 2,.

On graphs with α- and b-edge consecutive edge magic labelings

open access: yesIndonesian Journal of Combinatorics, 2022
Among the most studied graph labelings we have the varieties called alpha and edge-magic. Even when their definitions seem completely different, these labelings are related.

On the Graceful Cartesian Product of Alpha-Trees

open access: yesTheory and Applications of Graphs, 2017
A \emph{graceful labeling} of a graph $G$ of size $n$ is an injective assignment of integers from the set $\{0,1,\dots,n\}$ to the vertices of $G$ such that when each edge has assigned a \emph{weight}, given by the absolute value of the difference of the

Edge-Graceful Labelings of Connected Graphs

open access: yesElectronic Notes in Discrete Mathematics, 2016
Abstract Let G be a connected edge-graceful ( p , q ) -graph with q = k p + r , where k is an integer and 0 ≤ r p . In this paper, we prove that every edge-graceful labeling f of G induces [ ( k + 1 ) ! ] r [ k ! ] p − r number of edge-graceful labelings of G.

Graceful labelling of the union of paths and cycles

open access: yesDiscrete Mathematics, 1999
The authors show that \(C_5\cup P_n\) is graceful and \(C_s\cup P_n\) is graceful for every \(s\geq 5\) when \(n\geq (s+ 5)/2\). This result is another step towards settling the conjecture that \(C_s\cup P_n\) is graceful whenever \(n+ s\geq 7\).

Alpha graphs with different pendent paths

open access: yesElectronic Journal of Graph Theory and Applications, 2020
Graceful labelings are an effective tool to find cyclic decompositions of complete graphs and complete bipartite graphs. The strongest kind of graceful labeling, the α-labeling, is in the center of the research field of graph labelings, the existence of ...
