The Department of Mathematical Sciences is pleased to announce that Professor Martin Hairer of Imperial College, who is a Fields Medallist, will give a talk on Taming Infinities.

Abstract: Some physical and mathematical theories have the unfortunate feature that if one takes them at face value, many quantities of interest appear to be infinite! What's worse, this doesn't just happen for some exotic theories, but in the standard theories describing some of the most fundamental aspects of nature. Various techniques, usually going under the common name of renormalisation", have been developed over the years to address this, allowing mathematicians and physicists to tame these infinities. We will dip our toes into some of the conceptual and mathematical aspects of these techniques and we will see how they have recently been used to study equations whose meaning was not even clear until now.

Refreshments will be served prior to the lecture from 2.45pm.

All are welcome.
