Vafa-Witten Invariants of Projective Surfaces 2/5

By Richard Thomas

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
