Limit distributions of maximum vertex degree in a conditional configuration graph

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
We consider configuration graphs with N vertices. The degrees of the vertices are independent identically distributed  random variables following the power-law distribution with positive parameter τ.

Relating graph energy with vertex-degree-based energies [PDF]

open access: yesVojnotehnički Glasnik, 2020
Introduction/purpose: The paper presents numerous vertex-degree-based graph invariants considered in the literature. A matrix can be associated to each of these invariants.

Stability of Complement Degree Polynomial of Graphs

open access: yesمجلة بغداد للعلوم, 2023
     A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related. The objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of ...

On single-valued co-neutrosophic graphs [PDF]

open access: yesNeutrosophic Sets and Systems, 2018
In this paper, we introduce the notion of a single-valued co-neutrosophic graphs and study some methods of construction of new single-valued co-neutrosophic graphs.

Estimation of vertex degrees in a sampled network [PDF]

open access: yes2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
The need to produce accurate estimates of vertex degree in a large network, based on observation of a subnetwork, arises in a number of practical settings. We study a formalized version of this problem, wherein the goal is, given a randomly sampled subnetwork from a large parent network, to estimate the actual degree of the sampled nodes.

A Golden Ratio Inequality for Vertex Degrees of Graphs [PDF]

open access: yesThe American Mathematical Monthly, 2019
Motivated by the study of the crossing number of graphs, it is shown that, for trees, the sum of the products of the degrees of the end-vertices of all edges has an upper bound in terms of the sum of all vertex degrees to the power of $ ^2$, where $ $ is the golden ratio. The exponent $ ^2$ is best possible.

PREFERENTIAL ATTACHMENT WITH FITNESS DEPENDENT CHOICE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
We study the asymptotic behavior of the maximum degree in the preferential attachment tree model with a choice based on both the degree and fitness of a vertex.

Cost-based analyses of random neighbor and derived sampling methods

open access: yesApplied Network Science, 2022
Random neighbor sampling, or RN, is a method for sampling vertices with a mean degree greater than that of the graph. Instead of naïvely sampling a vertex from a graph and retaining it (‘random vertex’ or RV), a neighbor of the vertex is selected instead.

Sufficient Conditions for Graphs to Be k-Connected, Maximally Connected, and Super-Connected

open access: yesComplexity, 2021
Let G be a connected graph with minimum degree δG and vertex-connectivity κG. The graph G is k-connected if κG≥k, maximally connected if κG=δG, and super-connected if every minimum vertex-cut isolates a vertex of minimum degree. In this paper, we present
