16:640:551 - Abstract Algebra I

Anders Buch


Notes in preparation by Jonathan Brundan and Alexander Kleshchev


Standard course in Abstract Algebra for undergraduate students at the level of our Math 451.


This is a standard course for beginning graduate students. It covers Group Theory, basic Ring & Module theory, and bilinear forms. Group Theory: Basic concepts, isomorphism theorems, normal subgroups, Sylow theorems, direct products and free products of groups. Groups acting on sets: orbits, cosets, stabilizers. Alternating/Symmetric groups. Basic Ring Theory: Fields, Principal Ideal Domains (PIDs), matrix rings, division algebras, field of fractions. Modules over a PID: Fundamental Theorem for abelian groups, application to linear algebra: rational and Jordan canonical form. Bilinear Forms: Alternating and symmetric forms, determinants. Spectral theorem for normal matrices, classification over R and C. (Class supplement provided) Modules: Artinian and Noetherian modules. Krull-Schmidt Theorem for modules of finite length. Simple modules and Schur's Lemma, semisimple modules. (from Basic Algebra II) Finite-dimensional algebras: Simple and sem isimple algebras, Artin-Wedderburn Theorem, group rings, Maschke's Theorem.

Note: A Problem Session for 551 will be held on Wednesdays, 5:00pm-6:20pm in room 423 for the Fall semester. There is no need to register for the Problem Sessions.
