"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 tip 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.

Tutti gli interessati sono invitati a partecipare.
