Last two weeks of the course and I have finally started a page... better late than never right?

## Comments

- For people who are also in Topology, both DF and Lang have sections on the snake lemma, complexes, short exact sequences...etc

## Read Along

Here are some sections to check out in Dummit Foote (Third ed.) and Lang regarding what we have covered on Modules.

### DF

- Nov 17- Chap 10: Introduction to Module Theory
- Nov 22- Chap 12: Modules over Principal Ideal Domains.
- See p.464 (Theorem 6. Fundamental Theorem, Existence: Elementary Divisor Form) which is DF's statement of the Theorem we finished proving on Tuesday.

- Nov 24- Chap 10: Tensor Products of R-modules (p.359 Section 10.4)

#### Useful examples in DF

- DF, does a nice write up on F[x]-modules which I found to be quite helpful. See p. 340

### Lang

- Nov 17-Chap 3 p.117-127 For the basics.
- Nov 22- Chap 3 p.149-155
