Course Description

Algebraic geometry studies the geometry of spaces defined by polynomial equations. This module will study affine and projective varieties, focusing on examples and the dictionary between algebra and geometry. See also the description in the Undergraduate Handbook.

Recommended Texts

We will fairly closely follow Introduction to Algebraic Geometry by Brendan Hassett. Also highly recommended is Ideals, Varieties, and algorithms, by David Cox, John Little, and Donal O'Shea.
Both of these have electronic copies available through the library (for the Hassett book only one person can look at it at given time - so be careful to log out when done).
Other references you may want to consult include Undergraduate Algebraic Geometry by Miles Reid, Algebraic Geometry by Joe Harris, and the lecture notes of Andreas Gathmann (this contains many topics we will not get to). Other more advanced references include the classic by Hartshorne, and Shafarevich. If you want to buy copies of any of these books, I recommend first looking at a site like Alibris.co.uk, which searches multiple independent bookstores.

Announcements

First lecture Friday 3rd October.

Assessment

There will be homework assignments every two weeks. Homework assignments and due dates will be posted on the schedule webpage, which will also have the reading for the following week. You are encouraged to work on homework together, but you should write up the solutions yourself. No late homework will be accepted. The lowest homework score will be dropped, however, when calculating your homework mark. Homework will be due at 2pm on the Thursdays indicated on the schedule page.
In addition there will be a mini-project which will be due at the start of Term 2 (at 12pm on Wednesday, 7th January).
Your final mark for this module will depend 20% on your homework, 10% on the mini-project, and 70% on the examination in Term 3.

Mini-project

There are many possible first courses in algebraic geometry, and we cannot cover everything that might belong in such a course. In the mini-project you will learn one of these omitted topics, and write a five page description of the topic at a level suitable for reading by your classmates. The five page page-limit will be strictly enforced, and the font must be at least 11pt. Deadlines:
  • Topic choice: Friday of week 4 (24th October)
  • Final copy: 12pm, Wednesday, 7th January 2014.
The following is a (noncomprehensive) list of potential topics. More may be added over the first few weeks of term.
  • Bernstein's theorem
  • Algebraic curves
  • Abstract varieties
  • Connections with complex manifolds
  • Blow-ups
  • Algebraic groups
  • Secant varieties
  • Flag varieties
  • Cubic surfaces
  • Rational points
  • Applications to kinematics (eg Stewart-Gough platforms)
  • Applications to statistics
