Professor Martin Hairer, will be visiting Mathematical Sciences to deliver his lecture ‘Taming Infinities’, giving an outline of some of the ideas behind his work.
Professor Hairer is Regius Professor Mathematics at Warwick University. In 2014, he was awarded the Fields Medal, the Mathematical equivalent of the Nobel Prize.
The event will take place on:
18 May
Building 67 (Nightingale Building) Lecture theatre A (room 1027)
Highfield Campus
A drinks reception will be held afterwards in the Mathematical Sciences Student Centre

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.
Various techniques usually going under the common name of ‘renormalisation’ have been developed over the years to address this, allowing mathematics and physicist to tame these infinities.
Professor Hairer will explore some of the mathematical aspects of these techniques and will see how they have recently been used to make precise analytical statements about the solution of some equations whose meaning was not even clear until now.
