Expander graphs --- where combinatorics and algebra compete and
cooperate

** Abstract: **
Expansion of graphs can be given equivalent definitions in
combinatorial and algebraic terms. This is the most basic connection
between combinatorics and algebra illuminated by expanders and the
quest to construct them. The talk will survey how fertile this
connection has been to both fields, focusing on recent results.
