Prof. Richard THOMAS (Imperial College London)

Description

This course has 4 sections split over 5 lectures. The first section will be the longest, and hopefully useful for the other courses.

1. Sheaves, moduli and virtual cycles
2. Vafa-Witten invariants: stable and semistable cases
3. Techniques for calculation --- virtual degeneracy loci, cosection localisation and a vanishing theorem
4. Refined Vafa-Witten invariants
