Text: This time I did a book at the bookstore, but still the texts, my notes and homework are based on are available through Brown's library web page.
Make sure you can access these since reading - including independent reading - and homework problems will be assigned.

Notes in preliminary form:
Quick review
Cohomology


Presentation notes:
Enough injectives (following ogus)


Notes from a previous course (Some might be valuable for review):
Sheaves of modules
Introduction to resolution of singularities
A few presentations following Kollar
Crash course on cohomology


Subjects
Cohomology of schemes, algebraic curves and algebraic surfaces.


Basis for grading
I'll assign homework from the books, but I am not sure I will grade it. I will assign reading material. I will regularly assign material to present in class, which will be the primary grading mechanism. In fact the entire subject of curves and surfaces will be covered this way.

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.
