Identifying network structure similarity using spectral graph theory [PDF]
Applied 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

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

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

Geary’s c and Spectral Graph Theory [PDF]
Mathematics, 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 Theory of Infinite Quantum Graphs [PDF]
Annales Henri Poincaré, 2018 We investigate quantum graphs with infinitely many vertices and edges without the common restriction on the geometry of the underlying metric graph that there is a positive lower bound on the lengths of its edges. Our central result is a close connection

Shapes of Uncertainty in Spectral Graph Theory [PDF]
IEEE Transactions on Information Theory, 2020 We present a flexible framework for uncertainty principles in spectral graph theory. In this framework, general filter functions modeling the spatial and spectral localization of a graph signal can be incorporated. It merges several existing uncertainty relations on graphs, among others the Landau-Pollak principle describing the joint admissibility ...

Spectral graph theory of brain oscillations [PDF]
Human Brain Mapping, 2019 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.

Spectral theory of quantum graphs
, 2012 Diese Arbeit beinhaltet Untersuchungen von Spektralproblemen für Quantengraphen mit Potential. Einerseits analysieren wir die quantitative Abhängigkeit der Eigenwerte des Schrödingeroperators vom Potential. Andererseits verallgemeinern wir gewisse elementare Identitäten von der eindimensionalen Streutheorie auf Quantengraphen.

Discovering genetic ancestry using spectral graph theory. [PDF]
Genet 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.
