WLH 2112. (There **will** be section on Tuesday January 6, 2009.)

**Textbook:** *Contemporary Abstract
Algebra* by Gallian, 6th Edition. We will cover approximately Chapters 0-11
in Math 103A.

**Prerequisites:** The prerequisite is Math 109. Concurrent enrollment in
Math 109 is usually not recommended; please come talk to me if you want to take
this course and have not yet passed Math 109.

**Homework:** Homework will be assigned
weekly; the list of problems for the week will be posted on the class website.
Homework will be due in Discussion on Tuesday. Late homework will not be accepted, but
the lowest homework score will be dropped.

**Exams: **There will be 2 in-class midterms on **
Wednesday January 28** and **Wednesday February 25. **The final exam is on
**Friday March 20** from 3pm-6pm.
No books, notes, or calculators are allowed during exams. The Final Exam will be
cumulative and roughly the length of two midterms.

**Grading: **
*
***Final Grade **= homework
(25%) + 2 midterms (20% each) + final (35%).

**Description: **This is a first class in abstract algebra. The main
topic will be the theory of groups. Compared to Math 100A, this course goes more
slowly, is somewhat less proof-oriented, and spends more time on applications of
the theory. For most variations of the math major which require a course in
algebra, 103A suffices. If you are considering graduate study in mathematics,
however, you should take Math 100A instead.

**Academic honesty:** I expect you to abide by the university's policies.
Serious cases of dishonesty may be reported to the appropriate university
committee. The most straightforward kind of cheating which is obviously
disallowed is copying from a neighbor's exam, or consulting notes or the book
during an exam.

The honesty rules for homework are sometimes less obvious. So there is no
confusion, here are my particular rules.

- The homework you hand in should be your own written work, and your own
only. It is not acceptable to copy word for word, or paraphrase, the work of
another student in the class, or a solution found (say) on the internet or
in a solutions manual, and hand it in as your own work.

- You may work with others in the class (I am all for this), but be
careful not to violate rule 1 above. Certainly you can freely discuss
definitions, examples in the text, etc. with others to help you understand
them. For the homework problems, it is best to start by thinking about the
problems yourself, hard. You may see how to do some of them, but be stuck on
others. Wait a while, you will probably have additional insights the next
day (this is one reason it is important to start the homework early). You
can ask us or a friend for hints. Hopefully after more thought you will see
how to solve the ones you were stuck on. If not, and here and there a friend
tells you how to do a problem you were completely stuck on, and then you
write it up yourself using only your own understanding, that's OK. But this
should only be a problem here or there, not a significant fraction of them,
or else you won't learn how to work through these problems independently.

- Just to clarify further, reading through a friend's entire solution to a
problem which you did not think about yourself and then immediately writing
your own solution is not allowed. You are likely to end up writing a
paraphrase of the other solution and not really understand the proof, and
you won't gain the benefit that comes from thinking long and hard about the
problems.
