INTRODUCTION The study of eigenvalues and eigenvectors of various matrices associated with graphs play a central role in our understanding of graphs. The set of graph eigenvalues are termed the spectrum of the graph. Over the past thirty years or so, …

In mathematics, spectral graph theory is the study of the properties of a graph in relationship to the characteristic polynomial, eigenvalues, and eigenvectors of matrices associated with the graph, such as its adjacency matrix or Laplacian matrix. The adjacency matrix of a simple undirected graph is a … See more Two graphs are called cospectral or isospectral if the adjacency matrices of the graphs are isospectral, that is, if the adjacency matrices have equal multisets of eigenvalues. Cospectral graphs … See more Spectral graph theory emerged in the 1950s and 1960s.

A hypergraph is a pair where is a finite set and is a nonempty collection of subsets of . is called -uniform if. . is called a graph if it is 2-uniform. Our goal for this lecture is to explore the rudiments of the spectral theory of -uniform hypergraphs.
WebMar 24, 2024 · The largest absolute value of a graph's spectrum is known as its spectral radius . The spectrum of a graph may be computed in the Wolfram Language using Eigenvalues [ AdjacencyMatrix [ g ]].

WebFeb 21, 2024 · Clustering is one of the main tasks in unsupervised machine learning. The goal is to assign unlabeled data to groups, where similar data points hopefully get assigned to the same group. Spectral clustering is a technique with roots in graph theory, where the approach is used to identify communities of nodes in a graph based on the edges ...
