Graceful labeling of digraphs—a survey [PDF]
A digraph D with p vertices and q arcs is labeled by assigning a distinct integer value g(v) from to each vertex v. The vertex values, in turn, induce a value g(u, v) on each arc (u, v) where g(u, v) = (g(v) − g(u)) (mod q + 1) If the arc values are all distinct then the labeling is called a graceful labeling of digraph. In this survey article, we have

m -Bonacci graceful labeling [PDF]
We introduce new labeling called m-bonacci graceful labeling. A graph G on n edges is m-bonacci graceful if the vertices can be labeled with distinct integers from the set such that the derived edge labels are the first n m-bonacci numbers. We show that complete graphs, complete bipartite graphs, gear graphs, triangular grid graphs, and wheel graphs ...

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

Exploring Relationship Between Traditional Lattices and Graph Lattices of Topological Coding
It is known that there are no polynomial quantum algorithms to solve some lattice difficult problems. Uncolored graphic lattice and colored graphic lattice are the products of multidisciplinary intersection inspired by lattice theory. A uncolored graphic

A Study of Independency on Fuzzy Resolving Sets of Labelling Graphs
Considering a fuzzy graph G is simple and can be connected and considered as a subset H=u1,σu1,u2,σu2,…uk,σuk, |H|≥2; then, every two pairs of elements of σ−H have a unique depiction with the relation of H, and H can be termed as a fuzzy resolving set ...

Graceful Labeling of Hypertrees
Graph labeling is considered as one of the most interesting areas in graph theory. A labeling for a simple graph G (numbering or valuation), is an association of non -negative integers to vertices of G (vertex labeling) or to edges of G (edge labeling) or both of them.

Relaxed Graceful Labellings of Trees [PDF]
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.

Special Graceful Labelings of Irregular Fences and Lobsters
Irregular fences are subgraphs of $P_m \times P_n$ formed with $m$ copies of $P_n$ in such a way that two consecutive copies of $P_n$ are connected with one or two edges; if two edges are used, then they are located in levels separated an odd number of ...
