Graphs with Flexible Labelings [PDF]
Discrete & 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.

Two types irregular labelling on dodecahedral modified generalization graph
Heliyon, 2022 Irregular labelling on graph is a function from component of graph to non-negative natural number such that the weight of all vertices, or edges are distinct. The component of graph is a set of vertices, a set of edges, or a set of both. In this paper we

Distance labeling in graphs [PDF]
Journal 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 certain prime cordial families of graphs
Journal of Taibah University for Science, 2020 Graph labelling is an important tool in modelling real life problems. In the present paper, different graph families are studied for prime cordial labelling.

Detection number of bipartite graphs and cubic graphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 For a connected graph G of order |V(G)| ≥3 and a k-labelling c : E(G) →{1,2,…,k} of the edges of G, the code of a vertex v of G is the ordered k-tuple (ℓ1,ℓ2,…,ℓk), where ℓi is the number of edges incident with v that are labelled i. The k-labelling c is

Computing the total H-irregularity strength of edge comb product of graphs
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 A simple undirected graph = (V Γ, EΓ) admits an H-covering if every edge in E belongs to at least one subgraph of that is isomorphic to a graph H. For any graph admitting H-covering, a total labelling β : VΓ ∪EΓ→{1, 2, …, p} is called an H-irregular ...

Total edge irregularity strength of quadruplet and quintuplet book graphs [PDF]
ITM Web of Conferences, 2021 Let G= (V, E) be a finite, simple and undirected graph with a vertex set V and an edge set E. An edge irregular total k-labelling is a function f : V ᴗE → {1,2,…,k} such that for any two different edges xy and x’y’ in E, their weights are distinct.

Variable neighbourhood search for the minimum labelling Steiner tree problem [PDF]

The Electronic Journal of Combinatorics, 2018 A graph labeling is an assignment of integers to the vertices or edges, or both, subject to certain conditions. Graph labelings were first introduced in the mid 1960s. In the intervening 50 years nearly 200 graph labelings techniques have been studied in over 2000 papers. Finding out what has been done for any particular kind of labeling and keeping up
