Spectral graph theory of brain oscillations—-Revisited and improved [PDF]

open access: yesNeuroImage, 2022
Mathematical modeling of the relationship between the functional activity and the structural wiring of the brain has largely been undertaken using non-linear and biophysically detailed mathematical models with regionally varying parameters.

Identifying network structure similarity using spectral graph theory [PDF]

open access: yesApplied Network Science, 2018
Most real networks are too large or they are not available for real time analysis. Therefore, in practice, decisions are made based on partial information about the ground truth network. It is of great interest to have metrics to determine if an inferred

Geary’s c and Spectral Graph Theory [PDF]

open access: yesMathematics, 2021
Spatial autocorrelation, of which Geary’s c has traditionally been a popular measure, is fundamental to spatial science. This paper provides a new perspective on Geary’s c.

Spectral graph theory of brain oscillations. [PDF]

open access: yesHum Brain Mapp, 2020
AbstractThe relationship between the brain’s structural wiring and the functional patterns of neural activity is of fundamental interest in computational neuroscience. We examine a hierarchical, linear graph spectral model of brain activity at mesoscopic and macroscopic scales.

Controllability and heterogeneity of river networks using spectral graph theory approach [PDF]

open access: yesScientific Reports
River networks are important landscape features that have been extensively studied over many years. While seminal works have focused on characterizing the topological properties of river networks, the quantification of their spectral properties has ...

Discovering genetic ancestry using spectral graph theory. [PDF]

open access: yesGenet Epidemiol, 2010
AbstractAs one approach to uncovering the genetic underpinnings of complex disease, individuals are measured at a large number of genetic variants (usually SNPs) across the genome and these SNP genotypes are assessed for association with disease status.

A Few Examples and Counterexamples in Spectral Graph Theory

open access: yesDiscussiones Mathematicae Graph Theory, 2020
We present a small collection of examples and counterexamples for selected problems, mostly in spectral graph theory, that have occupied our minds over a number of years without being completely resolved.

On the spectral radius of VDB graph matrices

open access: yesVojnotehnički Glasnik, 2023
Introduction/purpose: Vertex-degree-based (VDB) graph matrices form a special class of matrices, corresponding to the currently much investigated vertex-degree-based (VDB) graph invariants. Some spectral properties of these matrices are investigated.

Spectral Sufficient Conditions on Pancyclic Graphs

open access: yesComplexity, 2021
A pancyclic graph of order n is a graph with cycles of all possible lengths from 3 to n. In fact, it is NP-complete that deciding whether a graph is pancyclic.

Geary’s c and Spectral Graph Theory: A Complement

open access: yesMathematics, 2023
Spatial autocorrelation, which describes the similarity between signals on adjacent vertices, is central to spatial science, and Geary’s c is one of the most-prominent numerical measures of it.
