Vafa-Witten Invariants of Projective Surfaces 4/5
Apparaît dans la collection : Richard Thomas - Vafa-Witten Invariants of Projective Surfaces
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
