Notes
Sheaves of modules

Subjects
I will start with as much of sheaves of modules and differentials as needed for the rest. Then we'll go through resolution of singularities in characteristic 0 following Kollár. Then we'll do divisors and algebraic curves and proceed as time permits.

The subject of resolution of singularities in characteristic 0 was traditionally considered scary. This is an outdated view which no longer is based on reality. One of my goals is that you will come to know that resolution of singularities - in characteristic 0 - is not so hard. When you go out into the world people will think you have superpowers.

Another goal is for you to help me prepare for my ICM talk.

Basis for grading
When we study material in Liu's book I'll assign weekly homework. When we study resolution of singularities, algebraic curves, and other topics if time permits, students will also present material from the sources in class and submit their notes. Grades will be based on these solutions, presentations and notes.

Solutions to problem sets are to be stapled.

Collaboration

You are encouraged to collaborate with other students in the class on your homework, although I suggest that you think carefully about each problem on your own first. You are required to write up your solutions separately and write the names of the students with whom you worked on the assignment. (You may only use the Internet as a general reference, at the level of generality of Wikipedia.)
You are also encouraged to collaborate on preparation of presentations.

How much time will this class take?

Roughly speaking, you should expect to spend twelve hours every week outside of class, including attending office hours, reviewing class material, doing problem sets, preparing presentations. In addition to three hours of class every week, I estimate a total of 15*13 = 195 hours of time spent on this class.
