Math 322: Group Theory

Fall Term 2017
Lior Silberman

General Information

This is the introductory course in algebra, intended for honours students. Students who wish to buy a single abstract algebra book should buy the book [1], which will serve you for both 322 and 323 and also covers the material of 422 to an extent. The gentler and less-terse alternative is the book [2]. If you want a group-theory specific textbook, the best book in my opinion is Rotman's (reference [3] below). You can download a copy by following the link while on the UBC network. That said, any book titled "Group Theory" (topic-specific) or "algebra" or "abstract algebra" (wide-coverage) is fine.


  1. Dummit and Foote, Abstract Algebra
  2. Gallian, Contemporary Abstract Algebra
  3. Rotman, An Introduction to the Theory of Groups, also available from SpringerLink.

During the course, we will study three classical theorems by Sylow. They are, of course, discussed in detail in the textbooks. Sylow's original paper from 1872 (written in French) is available online from the Göttingen University Library.

  2. Problem Set 2, due 21/9/2017 (typo in 1(a) fixed).

Lecture-by-Lecture information

Readings are generally from Dummit and Foote (sections marked "N" are in the lecture notes). Those reading Rotman can find the material there
