Description:

Expander graphs are families of finite graphs that are simultaneously relatively sparse and highly connected. Since their discovery in the fates 1960s, they have appeared in many seemingly unrelated areas of mathematics, from theoretical computer science to arithmetic and algebraic geometry, from representation theory to number theory. The goal of this book is to present the theory of expander graphs and to explore some of these rich connections. Besides a careful exposition of the basic parts of the theory, including the Cheeger constant, random walks and spectral gap characterizations of expander graphs, it contains many different constructions of various families of expander graphs. The applications that are surveyed in the last chapter try to communicate the remarkable reach of expander graphs in the modern mathematics.

The expander walk sampling lemma, due to Ajtai, Komlós & Szemerédi (1987) and Gillman (1998), states that this also holds true when sampling from a walk on an expander graph. This is particularly useful in the theory of derandomization , since sampling according to an expander walk uses many fewer random bits than sampling independently. An introduction to expander families and Ramanujan graphs. Tony Shaheen. CSU Los Angeles. Before we get started on expander graphs I want . to give a definition that we will use in this talk. A graph is regular if every vertex has the same degree (the number of edges at that vertex). A 3-regu...
