## Modern Algebra II

We would cover as many of the following topics as we have time for.

- Non-commutative rings: Jacobson Radical, Wedderburn-Artin Theorem, Modules over group algebras, irreducible representations, Maschke's theorem.
- Commutative rings: Primary decomposition of modules, Lasker-Noether Theorem, Krull Intersection theorem,
Krull dimension, Integral extensions, Going Up/Going Down Theorems, Dedekind domains and DVRs, Noether Normalization Lemma, Completion of a ring, Dimension theory and Hilbert polynomials.
