Links
Math links: I've found the following sites to be useful.
- Ravi Vakil's site has many great resources. He keeps a list of upcoming algebraic geometry conferences. The notes for his classes are also very useful - try the foundations course.
- Stephanie Yang's notes for Joe Harris' course on enumerative geometry and intersection theory.
- J.S. Milne's site has many well-written course notes.
- Kiran Kedlaya maintains a useful site on funding opportunities.
