Course format and syllabus
Grades will be based on weekly problem sets, a take-home midterm, and the three-hour final exam. The
course will cover (roughly) the following material:
-
Factorization in Rings
- UFDs, PIDs, Euclidean domains
- Factorization in polynomial rings
-
Modules over PIDs
- Structure Theory
- Consequences for Linear Algebra
-
Field Theory
- Theory of fields and field extensions
- Algebraic extensions
- Separability
- Splitting fields
- Field extensions and the fundamental theorem of Galois theory
- Applications and computations of Galois groups
-
Algebraic Geometry (provisional)
- Affine Algebraic sets
- The Nullstellensatz
- Affine, Projective, and abstract varieties
- Spectra of general rings
The first three sections of the course are basically drawn from the syllabus of the prelim exam, and
represent the material we MUST get through. For that part I will follow Dummit and Foote fairly closely.
For the remainder of the course I thought I'd talk some about algebraic geometry, but I'm
open to suggestions if there are other things people want to learn.
I'm not a huge fan of Dummit and Foote's approach to algebraic geometry, so my perspective on the
material will probably be somewhat different from theirs.
