Graduate Program

Information concerning the course Mathematics 552 (Abstract Algebra II) taught in Spring 2017 by J. Tunnell is kept here. The course will be a continuation of Mathematics 551. It will meet Monday and Thursday 12:00-1:20 in Hill 423. The following information is currently available about this course.



Jacobson, "Basic Algebra", Volumes 1 and 2, second edition. These volumes are currently available from Dover (


Any standard course in abstract algebra for undergraduates and/or Math 551. It will be assumed that students understand the concepts of groups, rings, modules, vector space and linear algebra, and finitely generated modules over principal ideal domains.


Topics: This is the continuation of Math 551, aimed at a discussion of many fundamental algebraic structures. The course will cover the following topics (and perhaps some others).

  1. Basic module theory and introductory homological algebra - most of Chapter 3 and part of Chapter 6 of Basic Algebra II: hom and tensor, projective and injective modules, abelian categories, resolutions, completely reducible modules, the Wedderburn-Artin theorem
  2. Commutative ideal theory and Noetherian rings - part of Chapter 7 of Basic Algebra II: rings of polynomials, localization, primary decomposition theorem, Dedekind domains, Noether normalization
  3. Galois Theory - Chapter 4 of Basic Algebra I and part of Chapter 8 of Basic Algebra II: algebraic and transcendental extensions, separable and normal extensions, the Galois group, solvability of equations by radicals

Course Format: There will be weekly homework assignments, and midterm and final exams.
