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.
Early career STEM researchers are encouraged to take part in one of the UK’s most prestigious opportunities to showcase their research: a national poster competition held at the heart of Parliament. This event invites early-stage researchers in science, technology, engineering, and mathematics (STEM) to present their work to Members of both Houses, fostering direct engagement between academia and policymakers.
The finals of STEM for BRITAIN 2026 will be held in Parliament on 17 March 2026.
22 September to 5 October.
