Description:
This course has 4 sections split over 5 lectures. The first section will be the longest, and hopefully useful for the other courses. - Sheaves, moduli and virtual cycles, - Vafa-Witten invariants: stable and semistable cases, - Techniques for calculation --- virtual degeneracy loci, cosection localisation and a vanishing theorem, - Refined Vafa-Witten invariants
