4d gauge theory and 2d CFT from 6d point of view

At Asian Winter School on String Theory, January 2011.

• Part 1: Basics of 6d N=(2,0) theory. S-duality of 4d N=4
• Part 2: 4d N=2 as 6d N=(2,0) compactified on C
• Part 3: Relation with 2d CFT

Here is the short mathematical file used for the demonstration.
