On Degree-Based Topological Indices of Petersen Subdivision Graph

open access: yesEuropean Journal of Mathematical Analysis, 2023
In this paper, we adequately describe the generalised petersen graph, expanding to the categories of graphs. We created a petersen graph, which is cyclic and has vertices that are arranged in the centre and nine gons plus one vertex, leading to the ...

On Divided-Type Connectivity of Graphs

open access: yesEntropy, 2023
The graph connectivity is a fundamental concept in graph theory. In particular, it plays a vital role in applications related to the modern interconnection graphs, e.g., it can be used to measure the vulnerability of the corresponding graph, and is an ...

A paradigmatic approach to investigate restricted hyper totient graphs

open access: yesAIMS Mathematics, 2021
Nowadays, the problem of finding families of graphs for which one may ensure the existence of a vertex-labeling and/or an edge-labeling based on a certain class of integers, constitutes a challenge for researchers in both number and graph theory. In this

Connectivity Analysis of Cyclically Balanced Fuzzy Graphs

open access: yesFuzzy Information and Engineering, 2015
The concepts of connectivity and cycle connectivity play an important role in fuzzy graph theory. In this article, cyclic cutvertices, cyclic bridges and cyclically balanced fuzzy graphs are discussed.

Connectivity Index in Vague Graphs with Application in Construction

open access: yesDiscrete Dynamics in Nature and Society, 2022
The vague graph (VG), which has recently gained a place in the family of fuzzy graph (FG), has shown good capabilities in the face of problems that cannot be expressed by fuzzy graphs and interval-valued fuzzy graphs. Connectivity index (CI) in graphs is

From Time–Frequency to Vertex–Frequency and Back

open access: yesMathematics, 2021
The paper presents an analysis and overview of vertex–frequency analysis, an emerging area in graph signal processing. A strong formal link of this area to classical time–frequency analysis is provided.

On the Vertex-Connectivity of an Uncertain Random Graph

open access: yesIEEE Access, 2020
In many practical problems, randomness and uncertainty simultaneously appear in one complex system or network. When graph theory is applied to these problems, these complex systems or networks are usually represented by uncertain random graphs, in which ...

On vertex and edge degree-based topological indices

open access: yesVojnotehnički Glasnik, 2023
Introduction/purpose: The entire topological indices (T Ient) are a class of graph invariants depending on the degrees of vertices and edges. Some general properties of these invariants are established.

On the Distribution of Vertex Energy of Connected Non-Regular Non-Bipartite Integral Graphs with Maximum Vertex Degree Four

open access: yesScientific Annals of Computer Science
The energy of a vertex in a graph plays a very important role in terms of its contribution to the total energy of a graph, a significant graph invariant in the field of chemical graph theory.

A central local metric dimension on acyclic and grid graph

open access: yesAIMS Mathematics, 2023
The local metric dimension is one of many topics in graph theory with several applications. One of its applications is a new model for assigning codes to customers in delivery services. Let $ G $ be a connected graph and $ V(G) $ be a vertex set of $ G $.
