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.

- Dummit and Foote, Abstract Algebra
- Gallian, Contemporary Abstract Algebra
- 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 GĂ¶ttingen University Library.

- The midterm exam will take place during class on Tuesday, October 17th. The midterm will include calculational and abstract problems, and also one problem asking for the statement of a definition from class.
- Examinable material includes everything up to the isomorphism theorems and the simplicity of A_n, and all problem sets up to PS5.
- For comparison here are the midterms from Fall 2014 (grade statistics) and Fall 2015 (grade statistics).
- For the calculational part of the midterm, see Sections 1,2 of the practice problem document.
- Here are the 2017 exam and its solution.

- There is both online homework and written homework (problem sets).
- The problem sets below are accessible to all; solutions are stored on a secure website; registered students can access them after first logging on to Connect.
- Problem set grade statistics.

- Problem Set 1, due 14/9/2017. Solutions.
- Problem Set 2, due 21/9/2017 (typo in 1(a) fixed). Solutions.
- Problem Set 3, due 28/9/2017. Solutions.
