Pure Maths Colloquium: Property tau

Presented by Marc Lackenby, University of Oxford

5 March 2007 16:00 in E101

How can one construct a computer network without bottlenecks? Is there
a method of efficiently shuffling a pack of cards? How does the spectrum
of the Laplacian on a manifold behave under finite-sheeted covers? How
can one detect `large' groups? Do hyperbolic 3-manifolds contain
essential surfaces? In my talk, I will show how these questions are
all related to an intriguing concept known as `Property tau'.
