From Gauge Theory to Khovanov Homology via Floer Theory

The goal of the lecture is to describe a gauge theory approach to Khovanov homology of knots, in particular, to motivate the relevant gauge theory equations in a way that does not require too much physics background.  I will give a gauge theory perspective on the construction of singly-graded Khovanov homology by Abouzaid and Smith.
