Seminar Algebraic Geometry (SAG) I'll describe how to define Vafa-Witten invariants -- and refined Vafa-Witten invariants -- of projective surfaces. Then I'll explain how to calculate some parts of the theory via degeneracy loci and "Carlsson-Okounkov operators". The talk describes different projects joint with Yuuji Tanaka, Davesh Maulik and Amin Gholampour.
