Radio Graceful Labelling of Graphs

open access: yesTheory and Applications of Graphs, 2020
Radio labelling problem of graphs have their roots in communication problem known as \emph{Channel Assignment Problem}. For a simple connected graph $G=(V(G), E(G))$, a radio labeling is a mapping $f \colon V(G)\rightarrow \{0,1,2,\ldots\}$ such that $|f(

Edge even graceful labelling of new families of graphs

open access: yesJournal of Taibah University for Science, 2019
Elsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling. A graph G is called edge even graceful if there is a bijection $f: E(G) \rightarrow \{2, 4,\ldots , 2q\} $ such that ...

Edge even graceful labelling of some book graphs

open access: yesJournal of Taibah University for Science, 2018
Elsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling if there is a bijection f from the edges of the graph to the set $\{2, 4,\ldots , 2q\}$ such that, when each vertex is ...

A new class of graceful graphs: k-enriched fan graphs and their characterisations

open access: yesCubo, 2021
The Graceful Tree Conjecture stated by Rosa in the mid 1960s says that every tree can be gracefully labelled. It is one of the best known open problems in Graph Theory.

PELABELAN ODD-GRACEFUL PADA GRAF PRODUK SISIR

open access: yesMajalah Ilmiah Matematika dan Statistika, 2022
Gnanajothi defined a graph with edges to be odd-graceful if there is an injective function such that if every edge is labelled with the resulting edge labels are . She proved that the graph obtained by joining one pendant to every vertex in is odd-

Edge even and edge odd graceful labelings of Paley Graphs

open access: diamondJournal of Physics: Conference Series, 2021
Edge even graceful labeling is a novel graceful labelling, introduced in 2017 by Elsonbaty and Daoud. A graph G with p vertices and q edges is called an edge even graceful if there is a bijection f: E(G) → {2, 4,. .

Graceful labeling of posets

open access: diamondInternational Journal of Mathematics And Computer Research
The concept of graph labeling was introduced in mid-1960 by Rosa. In this paper, we introduce a notion of graceful labeling of a finite poset. We obtain graceful labeling of some postes such as a chain, a fence, and a crown. In 2002 Thakare, Pawar, and Waphare introduced the ‘adjunct’ operation of two lattices with respect to an adjunct pair of ...

Characterizations of kites as graceful graphs

open access: yesCubo
We introduce and study an infinite family of graceful graphs, which we call kites. The kites are graphs where a path is joined with a graph "forming" a kite.

Relaxed Graceful Labellings of Trees [PDF]

open access: bronzeThe Electronic Journal of Combinatorics, 2002
A graph $G$ on $m$ edges is considered graceful if there is a labelling $f$ of the vertices of $G$ with distinct integers in the set $\{0,1,\dots,m\}$ such that the induced edge labelling $g$ defined by $g(uv)=|f(u)-f(v)|$ is a bijection to $\{1,\dots,m\}$. We here consider some relaxations of these conditions as applied to tree labellings: 1.
