the circle, isometry groups, free groups,
automorphism groups, Dihedral groups, symmetric
groups, matrix groups as in sections 1.2-1.5 and

Plan for
the week: We'll continue
with Chapter 9 on Polynomial Rings. We'll skip the
last section 9.6 because we've already proven the
Hilbert Basis Theorem and we're not going to cover
Groebner bases. Probably if there's time we'll
start on Chapter 10 (Modules) on Wednesday.
Depending on student interest, we could have a
problem session on Friday.
I won't have office hours on Wednesday (there's a
talk I'm planning to attend).

Plan for the week: We'll
continue with 10.3 and 10.4 (free modules and
tensor products). We'll skip 10.5 (exact
sequences) although we might come back to it later
in the semester. We'll cover chapter 11 (vector
spaces) very quickly because most of it is review.
The last section 11.5 is on tensor algebras. We
will cover that section more carefully. Depending
on student interest, we could have a problem
session on Friday.
