Overview of course:

Here is the syllabus for 611. Roughly speaking it correponds to Chapters 1--12 of Dummit and Foote. The full syllabus for the Graduate algebra sequence 611--612 is here.

(1) Group Theory.

Group actions. Counting with groups. p-groups and Sylow theorems. Composition series. Jordan-Holder theorem. Solvable groups. Automorphisms. Semi-direct products. Finitely generated Abelian groups.

(2) Rings.

Euclidean domain is a principal ideal domain (PID). PID is a unique factorization domain (UFD). Gauss Lemma. Eisenstein's Criterion.

(3) Modules.

Exact sequences. First and second isomorphism theorems for R-modules. Free R-modules. Hom. Structure Theorem for finitely generated modules over a PID. Rational canonical form. Jordan canonical form. Bilinear forms. Tensor product of vector spaces, Abelian groups, and R-modules. Right-exactness of the tensor product. Restriction and extension of scalars. Symmetric and exterior algebras.
