Title: Vibrating drums,
Cayley graphs and isospectral surfaces
Abstract: In
1966, Kac asked whether it is possible for a person with perfect pitch to
hear the shape of a drum.
That is, he wondered whether
two drums which sound exactly the same must be geometrically identical.
This question has a natural generalization to surfaces and higher
dimensional manifolds. After defining precisely what it means for us to
"hear" a drum, surface or manifold, we will then show how
Cayley graphs can be used to construct surfaces that sound the same, but
are geometrically distinct. If time allows we will also discuss some
original work related to this problem done by Seunghee Ye ('10) in his
Honors Thesis.
