Lecture Notes

The students in this class usually transcribe the lecture notes. Professor Moshkovitz selected notes from various years for the 2016 class. All student notes are used with permission. Some students agreed to publish their names along with their scribed notes, while others chose to publish anonymously.

In addition, there are notes and readings from other sources.
