This is an introduction to algebraic geometry, the study of the geometry of solutions to polynomial equations in several variables. The course will present theorems about algebraic curves of small degree and will develop the interplay between the geometry of affine and projective varieties and the algebra of polynomial rings.
Each of the topics listed below will occupy roughly two weeks of course time:
1. Plane conics
2. Cubic plane curves (elliptic curves) and the group law
3. Affine algebraic sets and the Nullstellensatz
4. Rings of functions on varieties
5. Projective varieties and birational equivalence
6. The 27 lines on a cubic surface
Prerequisites: Basic algebra through Galois theory. Familiarity with complex analysis is not required but algebraic geometry is much closer to complex analysis than to the analytic geometry of multivariable calculus.
Textbook: Miles Reid, Undergraduate Algebraic Geometry (Cambridge University Press, 1988 edition) The text is available online from the author.
We will also be using William Fulton's classic Algebraic Curves (also available online from the author)
Homework will be graded and should be handed in on time; the lowest grade will be dropped.
Final grades will be based on homework (20%), the midterm (30%), and the take-home final (50%).
