Comparative Study of Prism Octahedron Network via Eccentric Invariants

open access: yesJournal of Chemistry, 2023
Topological indices are empirical features of graphs that characterize the topology of the graph and, for the most part, are graph independent. An important branch of graph theory is chemical graph theory.

On the Dominant Local Resolving Set of Vertex Amalgamation Graphs

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2023
Basically, the new topic of the dominant local metric dimension which be symbolized by Ddim_l (H) is a combination of two concepts in graph theory, they were called the local metric dimension and dominating set. There are some terms in this topic that is

On the Edge Metric Dimension of Certain Polyphenyl Chains

open access: yesJournal of Chemistry, 2021
The most productive application of graph theory in chemistry is the representation of molecules by the graphs, where vertices and edges of graphs are the atoms and valence bonds between a pair of atoms, respectively.

THE GRAPH-REPRESENTATION APPROACH TO TOPOLOGICAL FIELD THEORY IN 2 + 1 DIMENSIONS [PDF]

open access: yesInternational Journal of Modern Physics A, 1992
An alternative definition of topological quantum field theory in 2 + 1 dimensions is discussed. The fundamental objects in this approach are not gauge fields as in the usual approach, but nonlocal observables associated with graphs. The classical theory of graphs is defined by postulating a simple diagrammatic rule for computing the Poisson bracket of

The partition dimension of a subdivision of a homogeneous firecracker

open access: yesElectronic Journal of Graph Theory and Applications, 2020
Finding the partition dimension of a graph is one of the interesting (and uncompletely solved) problems of graph theory. For instance, the values of the partition dimensions for most kind of trees are still unknown.  Although for several classes of trees

A Comparative Study of Three Resolving Parameters of Graphs

open access: yesComplexity, 2021
Graph theory is one of those subjects that is a vital part of the digital world. It is used to monitor the movement of robots on a network, to debug computer networks, to develop algorithms, and to analyze the structural properties of chemical structures,

Graph weights arising from Mayer and Ree-Hoover theories of virial expansions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We study graph weights (i.e., graph invariants) which arise naturally in Mayer's theory and Ree-Hoover's theory of virial expansions in the context of a non-ideal gas.

Graph-theoretic approach to dimension witnessing

open access: yesNew Journal of Physics, 2021
A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measurements, this problem can be addressed using only the input–output ...

Research and Application of Hypernetwork Energy

open access: yesJisuanji kexue yu tansuo, 2021
Graph energy plays an important role in research of graph theory. Graph energy and many other similar variants have been applied in many other types of graphs, e.g., undirected graphs, oriented graphs, mixed graphs, and so on.
