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 ...

Dispersed graph labellings [PDF]

open access: yesAustralas. J Comb., 2023
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 $DL(G)$.

Extending of Edge Even Graceful Labeling of Graphs to Strong r-Edge Even Graceful Labeling

open access: yesJournal of Mathematics, 2021
Edge even graceful labeling of a graph G with p vertices and q edges is a bijective f from the set of edge EG to the set of positive integers 2,4,…,2q such that all the vertex labels f∗VG, given by f∗u=∑uv∈EGfuvmod2k, where k=maxp,q, are pairwise ...

ODD HARMONIC LABELING ON Cm,n ⊵e C4 GRAPH

open access: yesJurnal Diferensial, 2023
Graph is an ordered pair of a vertex and edge set that related with various theories, one of them called labeling. There are a lot of types of graph labeling, one of them is odd harmonious labeling. The odd harmonious labeling is an injective function f :

Distance labeling in graphs [PDF]

open access: yesJournal of Algorithms, 2004
Summary: We consider the problem of labeling the nodes of a graph in a way that will allow one to compute the distance between any two nodes directly from their labels (without using any additional information). Our main interest is in the minimal length of labels needed in different cases.

On Antimagic Labeling for Some Families of Graphs

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
Antimagic labeling of a graph  with  vertices and  edges is assigned the labels for its edges by some integers from the set , such that no two edges received the same label, and the weights of vertices of a graph  are pairwise distinct.

Graphs with Flexible Labelings [PDF]

open access: yesDiscrete & Computational Geometry, 2018
For a flexible labeling of a graph, it is possible to construct infinitely many non-equivalent realizations keeping the distances of connected points constant. We give a combinatorial characterization of graphs that have flexible labelings. The characterization is based on colorings of the edges with restrictions on the cycles.

Modular Irregular Labeling on Double-Star and Friendship Graphs

open access: yesJournal of Mathematics, 2021
A modular irregular graph is a graph that admits a modular irregular labeling. A modular irregular labeling of a graph G of order n is a mapping of the set of edges of the graph to 1,2,…,k such that the weights of all vertices are different.
