Song of the Week: Dolly Mixture - Our Tune

Dolly Mixture were a few years too early. Around at the time of post-punk, they sound like they were from the late eighties or nineties, or, frankly, any time since. Debsey, Rachel and Hester never really made it, but Debsey Wykes has just told the tale in an autobiography.

Large mass limit of $G_2$ and Calabi Yau monopoles

Yang Li
(Cambridge)
Abstract

I will discuss some recent progress on the Donaldson Segal programme, and in particular how calibrated cycles (coassociative submanifolds, special Lagrangians) arise from the large mass limit of $G_2$ and Calabi Yau monopoles.

Developments in Vafa-Witten theory

Martijn Kool
(Utrecht)
Abstract

S-duality is an intriguing symmetry of (twisted) N=4 supersymmetric Yang-Mills theory on a four-manifold. When the four-manifold underlies a complex projective surface, it leads to the Vafa-Witten invariants defined by Tanaka-Thomas in 2017. I will discuss some developments related to Azumaya algebras, universality, Seiberg-Witten invariants, wall-crossing for Nakajima quiver varieties, the structure of S-duality, and modular curves (including relations to the Rogers-Ramanujan continued fraction and Klein quartic).
