Generating graceful unicyclic graphs from a given forest

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Acharya (1982) proved that every connected graph can be embedded in a graceful graph. The generalization of this result that, any set of graphs can be packed into a graceful graph was proved by Sethuraman and Elumalai (2005). Recently, Sethuraman et al. (

A structural approach to the graceful coloring of a subclass of trees [PDF]

open access: yesHeliyon, 2023
Let M={1,2,..m} and G be a simple graph. A graceful m-coloring of G is a proper vertex coloring of G using the colors in M which leads to a proper edge coloring using M∖{m} colors such that the associated color of each edge is the absolute difference ...

A survey and a new class of graceful unicylic graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
A graph G admits a graceful labeling if there is a one-to-one map f from the set of vertices of G to such that when an edge xy is assigned the label the resulting set of edge labels is When such a labeling exists, G is called graceful. Rosa showed that a

Edge odd graceful labeling of some path and cycle related graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2017
Solairaju and Chithra introduced a new type of labeling of a graph with vertices and edges called an edge odd graceful labeling if there is a bijection from the edges of the graph to the set such that, when each vertex is assigned the sum of all edges ...

Graceful labeling on torch graph

open access: yesIndonesian Journal of Combinatorics, 2018
Let G be a graph with vertex set V=V(G) and edge set E=E(G). An injective function f:V --> {0,1,2,...,|E|} is called graceful labeling if f induces a function f*(uv)=|f(u)-f(v)| which is a bijection from E(G) to the set {1,2,3,...,|E|}.

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 ...

Edge Odd Graceful Labeling in Some Wheel-Related Graphs

open access: yesMathematics
A graph’s edge labeling involves the allocation of symbols (colors or numbers) to the edges of a graph governed by specific criteria. Such labeling of a graph G with order n and size m is named edge odd graceful if there is a bijective map φ from the set

Graceful Labeling and Skolem Graceful Labeling on the U-star Graph and It’s Application in Cryptography

open access: yesJambura Journal of Mathematics, 2021
Graceful Labeling on graph G=(V, E) is an injective function f from the set of the vertex V(G) to the set of numbers {0,1,2,...,|E(G)|} which induces bijective function f from the set of edges E(G) to the set of numbers {1,2,...,|E(G)|} such that for ...
