**Notes**

Sheaves of modules

Introduction to resolution of singularities

**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traditionally considered scary.** This is an outdated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.

**Dates** (see also
the
academic calendar)

Class starts January 24.

Add date is February 6. Grade option date is
February 21 and Audit date March 9.

Between February 12 and 16 there will be
special lectures and no office hours.

February 19 Brown is out for
President's Day.

Spring break March 26-30.

let me know if you want to go to
AGNES April

Watch for possible updates regarding April 16-20.

Last class May 7 (during reading period).
