SYLLABUS
COURSE:
ALGEBRAIC STRUCTURES II (3)
Ring theory including the Artin-Wedderburn theorem, the Jacobson radical.
Commutative algebra, Noetherian rings, and Dedekind domains.
PREREQUISITE: MATH 520 or consent of department
TEXT: Introductory Lectures on Rings and Modules, Cambridge University Press, and supplementary lecture notes on commutative rings. Recommended reference: Algebra, by Hungerford
SYLLABUS:
These are the topics listed for the comprehensive exam in algebra.
Rings and Modules:
Modules, simplicity, semisimplicity, chain conditions, tensor products,
Jacobson radical, density theorem, Wedderburn-Artin theorem,
finitely generated modules over a principal ideal domain,
canonical forms.
Unique factorization, Euclidean domains, principal ideal domains,
polynomial rings, maximal, prime, and primary ideals,
Noetherian rings, Hilbert basis theorem, Lasker-Noether decomposition,
integral elements, integral closure, fractional ideals, Dedekind domains.
To prepare for these topics, I plan to cover the following sections of the text. (Chapter 5 is a set of supplementary notes available on the web, and is not included in the published version of the book). The emphasis of the book is on noncommutative rings, and so Chapter 4 covers the representation theory of finite groups as an application of the general theory developed in the previous chapters.
CHAPTER 1: RINGS (62 pages)
CHAPTER 2: MODULES (74 pages)
CHAPTER 3: STRUCTURE OF NONCOMMUTATIVE RINGS (34 pages)
CHAPTER 5: IDEAL THEORY OF COMMUTATIVE RINGS (36 pages)
TENTATIVE SCHEDULE OF LECTURES
Chapter 1, Rings: 3 weeks
Chapter 2, Modules: 6 weeks
Chapter 3, Noncommutative Rings: 3 weeks
