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 ...

Taylor’s power law for the N-stars network evolution model

open access: yesModern Stochastics: Theory and Applications, 2019
Taylor’s power law states that the variance function decays as a power law. It is observed for population densities of species in ecology. For random networks another power law, that is, the power law degree distribution is widely studied.

Directed random geometric graphs: structural and spectral properties

open access: yesJournal of Physics: Complexity, 2022
In this work we analyze structural and spectral properties of a model of directed random geometric graphs: given n vertices uniformly and independently distributed on the unit square, a directed edge is set between two vertices if their distance is ...

Random Trees in Random Graphs [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
We show that a random labeled n n -vertex graph almost surely contains isomorphic copies of almost all labeled n n -vertex trees, in two senses. In the first sense, the probability of each edge occurring in the graph diminishes as n n increases, and the set of trees referred to as "almost all" depends

On hamiltonicity of uniform random intersection graphs

open access: yesLietuvos Matematikos Rinkinys, 2010
We give a sufficient condition for the hamiltonicity of the uniform random intersection graph G{n,m,d}. It is a graph on n vertices, where each vertex is assigned d keys drawn independently at random from a given set of m keys, and where any two vertices

Two modified Zagreb indices for random structures

open access: yesMain Group Metal Chemistry, 2021
Random structure plays an important role in the composition of compounds, and topological index is an important index to measure indirectly the properties of compounds.

The number of planar graphs and properties of random planar graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We show an asymptotic estimate for the number of labelled planar graphs on $n$ vertices. We also find limit laws for the number of edges, the number of connected components, and other parameters in random planar graphs.

Revan Sombor indices: Analytical and statistical study

open access: yesMathematical Biosciences and Engineering, 2023
In this paper, we perform analytical and statistical studies of Revan indices on graphs $ G $: $ R(G) = \sum_{uv \in E(G)} F(r_u, r_v) $, where $ uv $ denotes the edge of $ G $ connecting the vertices $ u $ and $ v $, $ r_u $ is the Revan degree of the
