Sometimes artists become better known for their lifestyle or fashion tastes than the work without which we wouldn't know or care about them - Van Gogh, Bowie, even Taylor Swift. Jim Morrison of the Doors fits that bill, in his case for his death and grave as much as his life. But he and the band wrote some songs. That's where it all starts and ends.

Vafa-Witten invariants from modular anomaly

Sergey Alexandrov
(Montpelier)
Abstract
I'll present a modular anomaly equation satisfied by generating functions of refined Vafa-Witten invariants 
for the gauge group $U(N)$ on complex surfaces with $b_1=0$ and $b_2^+=1$, 
which has been derived from S-duality of string theory.
I'll show how this equation can used to find explicit expressions for these generating functions
(and their modular completions) on $\mathbb{CP}^2$, Hirzebruch and del Pezzo surfaces.
The construction for $\mathbb{CP}^2$ suggests also a new form of blow-up identities.

I work in the field of geometric group theory. This is a pretty broad heading, but for me it means that the goal is to understand infinite groups, and the strategy is to get them to act on nice metric spaces that we know a lot about. 

It's a little-known fact that Fibonacci was a keen marathon runner.

Okay, he wasn't but he could be an invaluable help if you are a keen marathon runner.

Josh Bull is very keen.
