S-dualities in 4d N=2 supersymmetric theories

At ICTP Spring School, 27th, 28th, 30th, 31st of March 2015.

• (video) 2d undeformed YM and 2d q-deformed YM
• (video) S-duality of SU(2) with N_f=4 and the superconformal indices
• (video) Interpretation via 6d N=(2,0) theories
• (video) Generalization to SU(N)

Handwritten notes are available, but might be hard to read.

Here is the short mathematical file used for the demonstration.

There are again big overlaps between my other lectures. This time I decided to talk about the 2d (q-deformed) YM itself, and to stick to superconformal indices rather than anomalies.

I re-uploded the videos to youtube so that they can be viewed on more mobile devices. The original ones (and those by other lecturers) are available from the official page.
