The bulk of this course will be the material in Chapters 10, 12, and 15 of Dummit
and Foote's text. We will begin with the basics of module theory given in Sections 10.1, 10.2, and 10.3, and then move on to the structure of modules over a PID in Chapter 12. We will then return to Section 10.4 to talk about tensor products of modules, followed by Section 11.5 on tensor algebras. This will hopefully take roughly half of the semester, at which point we will begin talking about commutative algebra in Chapter 15. We will see how far we get on that topic, and also consider going back to Section 10.5 to talk about exact sequences.
|Meeting Time:||MWF 9 - 9:50
|Location: ||Zoom/Jones 306|
Office Hours: All will be on Zoom, times TBD.
|Textbook:||Abstract Algebra (Third Edition) by
David S. Dummit and Richard M. Foote |
| Grade |
| Class Participation - 10%, Homework - 60%, Final Exam - 30%. The
grading scale will be the standard 10 percentage point scale, so that a final
score of 93 or higher is an A, 90-92 is an A-, 87-89 is a B+, 83-86 is a
B, 80-82 is a B-, 77-79 is a C+, 73-76 is a C, 70-72 is a C-, etc. |
|Attendance & Lecture Policy:||It is expected that you attend all
lectures (whether on Zoom or in the classroom), with exceptions minimized. It is greatly appreciated when you
are on time. Please do your best to stay awake and attentive during
lecture, please do not email or text during lecture, and keep all cell
phones/hand held devices/tablets/laptops put away during lecture (unless
you are specifically writing notes on a tablet). While it is
understandable that you may miss a lecture here and there, or be sleepy in
class once in awhile, repeated absences, late arrivals, naps, or general
non-attentiveness will negatively affect your class participation score.
|Prerequisite: || Math 430 - Abstract Algebra II ||
Dates & Course Announcements:
There will be no midterm. The final exam
will be a take-home exam, and due by the end of our final exam time slot, which
is Fri, Nov. 20, 9 AM-12 Noon (so the take-home final will be due at noon that
- All relevant announcements will be listed here. Check back frequently (don't forget
to refresh your browser) for updates.
- Important Dates and Class Holidays:
- Fri, Aug 28: ADD/DROP DEADLINE
- Mon, Oct 12: WITHDRAW DEADLINE
- Fri, Nov 13: LAST DAY OF CLASS
- Fri, Nov 20, 9:00 AM - 12 Noon - FINAL EXAM
- (8/19) I will determine regular office hours after the add/drop period.
I will not have any office hours during this short week, unless they are requested (which is welcomed).
- (10/23) Apart from the 3 problems assigned for HW 10, there are also the two optional problems which came up in the notes from Day 28. There is no due date for these, just anytime by the end of the last day of classes.
Homework problems will be a very important
part of the course, and there will be homework assigned almost every week.
Proofs and computations should be written
carefully and neatly, with attention paid to the completeness of your argument
and clarity of your steps. Individual homework
assignments should be written up by yourself, although some collaboration while
working on the homework is fine, and encouraged as long as the work you turn in
is your own formulation of a solution. You should not, under any
circumstances, attempt to copy solutions to problems online
(although I know this is very tempting), as this will have to be treated as plagiarism. Instead, email me for a hint, or
discuss problems in a group of classmates.
Homework problems will each be graded out of 10 points. Your homework score
will be based on your individual problem scores, rather than your scores on
assignments. In particular, there will be at least 50 problems assigned
for homework throughout the semester. Your total Homework score for the course
will be based on your best 45 problem scores, along with full credit
for 5 other earnestly attempted problems which are turned in on time. Your homework counts for 60% of your grade, which breaks down as your best
50 scores out of 10 points each, plus full credit for 10 attempted problems.
Homework problems are due on the posted due date at the start of class, either turned in as a hard
copy (if we move to the classroom), or emailed to me as a pdf of a latex file, or preferrably as just a latex file which I can then make comments on within the latex file directly. Homework is considered on time if it is turned in, or in my inbox,
at most 10 minutes after the start of class.
A total of 10 Homework problems throughout the semester may be turned in up to
2 weekdays late (by 5 PM in my office or inbox) without penalty. No other late homework will be accepted for
scoring (unless you have specific accommodations). All homework problems and
their due dates will be listed below.

Math Major Writing Requirement (Math 300):
If you are a math major, and you would like to complete your major writing
requirement through a writing assignment in this class, please let me know in
the first week of class. This writing assignment will not count towards your
grade in this class, but will rather just serve as your Major Writing
Requirement (Math 300). You should only do this if all of the following hold:
(1) you are not doing an honors thesis in Mathematics, (2) you are not doing
your COLL 400 requirement in Mathematics, and (3) you are a senior. If you decide to do this, you must write your paper on
a topic in Abstract Algebra (or a closely related subject) approved by me, and you must keep to a schedule of turning in
drafts we agree on at the beginning of the semester in order to get credit.

federal laws and university policy. Any student who feels they may need an
accommodation based on the impact of a learning, psychiatric, physical, or
chronic health diagnosis should contact Student Accessibility Services staff
