I will first introduce the notion of stability for a steady state solution to an evolution equation and it's connection to spectral theory. Then I will define the essential spectrum for a linear operator and discuss Nussbaum's formula for computing the essential spectral radius. To conclude I will describe how Nussbaum's formula leads to one of the key ideas in a stability result of Vishik.

I will talk about some interesting properties of Dean knots and how they fit into the study of SFS surgeries.

This semester we are studying topological quantum computation, roughly following http://arxiv.org/pdf/0707.1889?fname=cm&font=TypeI

In this talk I'll describe an approach to the Riemann Hypothesis which involves finding a good `mollifier' for the Riemann zeta-function.

Note the unusual date for this seminar.
