Title: Mochizuki's formula and the horizontal Vafa-Witten invariants

Abstract: In this lecture compute the horizontal Vafa-Witten invariants, 
by using Mochizuki's formula, which allows to reduce the computation to 
Hilbert schemes of points.

Then one can localization in a very similar way as for the vertical 
Vafa-Witten invariants. This computation confirms some of the 
predictions of S-duality in ranks 2 and 3.

Furthermore, combining with the computations of $S$-duality we predict 
the generating functions for the horizontal Vafa-Witten invariants in 
rank at most 5.
