03/14/08: I will have to leave today at 4:20 pm, so my office hours
will be somewhat shortened. Sorry! Have a great break and do not
forget about the homework!

02/13/08: Our guest speaker's flight has been delayed, and we will
have our normal class on Wednesday. The guest speaker will be talking
in class on Friday, regular classroom, regular time.
02/07/08: The class on Wednesday, February 13, will be joint with a
Special Colloquium. It will take place during the class time, at 2:30,
but in Vincent Hall 570. The speaker will be Duiliu-Emanuel Diaconescu
from the High Energy Physics Theory group at Rutgers, New Brunswick,
and he will talk on "Extremal transitions and localization in
Gromov-Witten theory." It is a colloquium talk, so it should be
accessible to everybody. And this an outstanding young theoretical
physicist who uses algebraic geometry very seriously. It should be a
good opportunity for you to see which trends in physics influence the
development of Algebraic Geometry. Below is the abstract of the talk.
Abstract: Gromov-Witten theory is the enumerative theory of curves on algebraic varieties. Many important developments in this field, such as mirror symmetry and integrability results, are based on the Atiyah-Bott localization theorem. In this talk we will formulate a series of conjectural results in Gromov-Witten theory obtained via extremal transitions and large N duality, emphasizing their relation with the standard localization approach.
02/07/08: Hint to the homework. Showing that S' is an integrally
closed domain may be tricky, unless you read the second half of the
proof of Theorem II.5.19.
02/04/08: I have removed Problem II.7.8 from Problem Set 1. Given that
the homework is due on Friday, I have added more office hours, Wed
3:30-5:00, for this week.
01/30/08: The first homework, due February 8, is posted. Good luck!
01/30/08: I will be out of town at a conference on Friday, February 1:
no class meeting, no office hours that day.
