One of the best resources is 'Spectra of Graphs' by Brouwer and Haemers and can be found online at: Another good reference is Biggs' 'Algebraic Graph Theory' as well as Godsil and Royle's 'Algebraic Graph Theory' (same titles, different books; I personally think Biggs is somewhat dated but more accesible for beginners). Chung's 'Spectral Graph Theory' book focuses mostly on the 'normalized' Laplacian, but this is also good to look into. The best part of that book are the first seven chapters, and the first four chapters are available online (in fact this is the best place to download these as they have been updated since publication): Chung and Butler wrote a follow up survey that is also online (though this does not contain proofs and is just a collection of results and pointers): • • • •.
Spectral graph theory studies connections between combinatorial properties of graphs and the eigenvalues of matrices associated to the graph, such as the adjacency matrix and the Laplacian matrix. Spectral graph theory has applications to the design and analysis of approximation algorithms for graph partitioning problems, to the study of random walks in graph, and to the construction of expander graphs. Download edi 1300 keygen photoshop cs2. It also reveals connections between the above topics, and provides, for example, a way to use random walks to approximately solve graph partitioning problems.
In this series of lectures we will introduce the basics of spectral graph theory, we will prove the discrete Cheeger inequalities, and see them as (i) a way to approximate the sparsest cut problem, (ii) an approach to bound the mixing time of random walks, and (iii) a way to certify expansion in graphs. We will then consider various generalizations of this result, such as higher-order Cheeger inequalities, a Cheeger-like inequality for the largest eigenvalue of the Laplacian, and the expander mixing lemma and its inverse. Each of these more advanced results will also be interpreted as the analysis of an approximation algorithm for a graph partitioning problem.
