  1. 1. Cospectral graphs : What properties are determined by the spectrum of a graph?

    University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

    Author : Erik Sundström; [2023]
    Keywords : graph theory; graph; graphs; spectral graph theory; cospectral graphs; adjacency matrix; adjacency matrices; graph spectrum; spectrum; graph spectra; spectra;

    Abstract : This paper was written as a bachelor thesis in mathematics. We study adjacency matrices and their eigenvalues to investigate what properties of the corresponding graphs can be determined by those eigenvalues, the spectrum of the graph. The question of which graphs are uniquely determined by their spectra is also covered. READ MORE

  3. 2. Properties of Discrete Laplacians With Application on Brain Networks

    University essay from KTH/Matematisk statistik

    Author : David Thinsz; [2022]
    Keywords : Graph Laplacian; Combinatorial Laplacian; Persistent Laplacian; Topological data analysis; Spectral theory; Homology; Clustering.; Graf-Laplacian; Kombinatorisk Laplacian; Beständig Laplacian; Topologisk dataanalys; Spektralteori; Homologi; Klustring.;

    Abstract : This thesis investigates three discrete Laplace operators: the graph Laplacian, combinatorial Laplacian, and the more recently introduced persistent Laplacian. We discuss how these operators relate to each other and study their spectral properties. The graph Laplacian is a well-studied operator that plays a central role in spectral graph theory. READ MORE
