Here are notes for lecture 3, and notes for lecture 7.
I wrote a little more about holomorphic and meromorphic functions after I actually took 6120. We had to give a "final presentation". (Here are notes.)
Although this doesn't really belong here, thanks to the "complex analysis" reading group I got to know Tood Lensman better and eventually I read some Calculus of Variations, for which I wrote this "writeup".
