Text

N. Lauritzen, Concrete Abstract Algebra, Cambridge. ISBN 0-521-53410-0.  There is a copy on reserve in the Main Library. Other books on the subject can also be found  (start browsing around QA 171).

Homework

There will be weekly homework assignments due on Thursdays. The homework is the most important part of the course. Most of your learning will take place while doing it. We will not accept late homework except in very unusual circumstances. We will, however, drop the lowest homework grade.

Exams

Midterm, Tuesday 9th October.
Final exam, Wednesday 5th December.

Calculators, books, notes etc are not permitted in either exam. Please bring your student ID to both exams.

Please note that there are no make-up or alternate exams, so make sure you do not make travel plans, work plans etc that will conflict.

Grading

Your grade will be based on the homework (10%), the midterm (30 or 40%), and the final (60 or 50%), whichever gives you the best grade.

Since this is a Mathematics Honours course,  students will primarily be expected to construct proofs involving fundamental and advanced ideas of the course. At least 80% of your grade will come from writing proofs.

Working together and academic integrity

We have no objection in principle to collaboration on the homework, provided that it is done in a way that maximizes the benefit of the homework to all people involved. (One person simply telling another how to do a problem totally defeats the purpose of the problem.) It is our opinion that you get maximum benefit from a homework problem if you work hard on it alone before combining your ideas with someone else's. In any case, the paper that you turn in with your name on it should represent your own solutions, written in your own words, regardless of whether you arrived at some of those solutions in collaboration with others.

In particular, you may not simply copy someone else's homework and turn it in as your own. This will be treated as a violation of UBC's Academic Integrity Code. Similarly, copying solutions that you might find on the web or from some other source is illegal. We take academic integrity very seriously and will follow university procedures in all cases of suspected cheating (which may result in expulsion).

There is anecdotal evidence that quite a bit of cheating occurs on campus. In an effort to prevent one common form of cheating, we will xerox a random sample of exam books before returning them.
