Welcome to Spectral Graph Theory homepage

Course Description

In this course we will discuss the connection between the spectrum of a matrix associated with a graph, to some of its combinatorial properties (such as diameter, connectivity, chromatic number etc.). Then we shall learn on the second eigenvalue and expansion, random walks, constructions of expander graphs and some of their applications.
