## Kassel: Ore, Noether, Gauss

### Sjoerd Crans – 4 December 1996

I did sections I.7, I.8 and IV.4 of Kassel's book (I didn't have time for the announced "Gauß" part, section IV.2), noting a little misprint on the bottom of page 19: a_{d,i} should be a_{n,i} and P_{d,i} should be P_{n,i}, noting the proofs of Proposition IV.1.1(a) and Lemma IV.4.2 are equal, and noting that GL_q (2) and SL_q (2) are Noetherian too, because they are quotients of (a simple Ore extension of) M_q (2).
