However, substantial revision is clearly needed as the list of errata got longer. For the purely mathematical approach, Reinhard Diestel's book is both excellent and affordably priced, with a free PDF preview available from the author. Graph drawing using the Laplacian, Unit 4. Spectral theory of real symmetric matrices, The extreme eigenvalues of the adjacency matrix, Graph partitioning and Cheeger's inequality, Explicit constructions of expander graphs, Explicit constructions of expander graphs, The lectures take "place" on Tuesday 9:00-12:00 via. Course description: Spectral graph methods use eigenvalues and eigenvectors of matrices associated with a graph, e.g., adjacency matrices or Laplacian matrices, in order to understand the properties of the graph. Spectral graph theory is the study of a graph via algebraic properties of matrices associated with the graph, in particular, the corresponding eigenvalues and eigenvectors. . We invite you to a fascinating journey into Graph Theory — an area which connects the elegance of painting and the rigor of mathematics; is simple, but not unsophisticated. Spectral methods • Understanding a graph using eigen values and eigen vectors of the matrix • We saw: • Ranks of web pages: components of 1st eigen vector of suitable matrix • Pagerank or HITS are algorithms designed to compute the eigen vector • Today: other ways spectral methods help in … Spectral Graph Theory, Fall 2019 Time: M-W 2:30-3:45. In particular, after a short linear algebra refresher, tentatively, we plan on covering. This course is about applications of linear algebra to graph theory and to graph algorithms. Access. Algebraic graph theory by Godsil and Royle. Spectral graph theory is the study of a graph via algebraic properties of matrices associated with the graph, in particular, the corresponding eigenvalues and eigenvectors. Newman, “Networks: An Introduction”, Oxford University Press, 2010. Spectral Graph Theory, Fall 2015 Applied Mathematics 561/ Computer Science 662 . The main course work is the course project. These are lecture notes that are based on the lectures from a class I taught on the topic of Spectral Graph Methods at UC Berkeley during the Spring 2015 semester. While the adjacency matrix depends on the vertex labeling, its spectrum is a graph invariant, The main objective of spectral graph theory is to relate properties of graphs with the eigenvalues and eigenvectors (spectral properties) of associated matrices. weighted digraph), which is a more general type of graph than the type de ned in Chapter 1 of Spielman’s book. This course is about understanding graphs by using the methods of Linear Algebra. Search.

Daniel Spielman's book (incomplete; available online). Graph partitioning and Cheeger's inequality, Unit 9. Today, we The course aims to bring the students to the forefront of a very active area of research. The adjacency matrix of a simple graph is a real symmetric matrix and is therefore orthogonally diagonalizable; its eigenvalues are real algebraic integers. The recitation, by Shir, is in the following hour. This is a research-oriented graduate course in spectral graph theory. Lecture 11: Introduction to Spectral Graph Theory Rajat Mittal IIT Kanpur We will start spectral graph theory from these lecture notes. The requirements include two presentations and a written report. Submissions are in pairs. Office Hours: Friday, 3:00 - 4:00 . On the other hand, most of our examples are … Guido Caldarelli, “Scale-Free Networks”, Oxford University Press, 2007. Explicit constructions of expander graphs, The recitation notes may contain Hebrew letters, Recitation 2 - operations on graphs and the resulted spectrum, Recitation 3 - group theory and characters recall; Cayley graphs, Recitation 5 - Hoffman's lower bound on the chromatic number, Recitation 8 - Cont last time; The Gaber-Galil expander, Recitation 9 - Cont the Gaber-Galil construction. The interconnections between properties of graphs and the eigenvalues of some matrices associated with graphs are studied.
