The theory of Ramanujan graphs has become significant
in communication theory in that it solves an important
extremal problem. However, their explicit construction
is still shrouded in mystery. At present, all explicit
constructions rely heavily on number theory, algebraic
geometry and representation theory. In this talk,
we will give a leisurely survey of this exciting area.
The talk should be accessible to undergraduates.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
