Vafa-Witten invariants for projective surfaces II: semistable case
<p>We propose a definition of Vafa-Witten invariants counting semistable Higgs pairs on a polarised surface. We use virtual localisation applied to Mochizuki/Joyce-Song pairs.</p> <br/> <p>For KS ≤ 0 we expect our definition coincides with an alternative definition using weig...
