Math stuff I'd like to learn more about:
- Theory of Species (category theoretical combinatorics).
- Generating Functions.
- Category theory.
- Problem sheet:
show that each of theses 66 sets are counted by the Catalan numbers
- Kiyoshi Igusa's page from the Algebra
class that he taught in Spring 2002. Also, the undergrad Algebra
course from Fall 2002.
