Meeting time: MWF 10:00-10:50. We meet in PHY 109.


Prerequisites: Undergraduate linear algebra (MAS 3105), abstract algebra (MAS 4301), and Algebra I (MAS 5311). Although we will develop each topic from the basics, the pace and depth will make the course challenging. The prerequisites will give you a foundation upon which to build your understanding. In this course you will be required to generate and write proofs. The prerequisites will have given you some facility in this. (Of course it is not expected that you have completely mastered these skills when you begin the course).

Text: ''Algebra, a graduate course'' by I. Martin Isaacs. ( publisher) ( Amazon) ( Barnes and Noble) I will ask the library to keep its copy on reserve. We will cover much of Part II in this course. Although slightly reorganized, together this meets most of the content for Algebra I and II described in the course description.

Homework: There will be 4 to 8 problems assigned from each section covered. A few of them will be graded, some will earn credit for being turned in. The homework is intended to give you problems to practice the material which we are covering in class. You are likely to find that most of your understanding comes from doing problems. I do not expect that students will do every problem, but they should attempt most of the problems and turn in at least half of them completed over the course of the semester for a satisfactory grade on homework. Homework should be turned in within 2 weeks of the day it is assigned.

Exams: There will be a take-home mid-term exam on Chapters 16 - 19 handed out in class on Friday, February 29 and due at the beginning of class on Friday, March 7. There will be a take-home final exam covering Chapters 20--27 given out Monday, April 25 and due Monday, May 2 by noon (the allocated time for the final exam). There will be no make-up exams or extra time granted to take the exams. If you are unable to turn either exam in strictly on time, you must make arrangements with the teacher before it is due.

During the exam periods you may ask me about the exams, you may consult your notes, and you may consult the textbook. No other source of information may be sought or used, including but not restricted to your classmates, your classmates' notes, your friends, other professors, books other than the Isaacs' Algebra, online information sources such as webnotes and math newsgroups. You are not to discuss the exams with your classmates during this time (even comments that some problem is easy can provide improper assistance).


Attendance: Attendance will not count toward your grade. However, students are responsible for material presented in lecture even if it is not in the text and vice versa.

Grades: Midterm 40%, Final 40%, Homework 20%.

Notes and Tapes: You are expected to take notes and/or tapes. They may not be sold or offered for sale.

Course Objectives: (a) Learn some interesting algebra.
(b) Prepare for Algebra Qualifying exam (along with Advanced Linear Algebra--MAS 5107). Among the topics of the qualfying exam to be covered in this course are field theory up to the fundamental theorem of Galois theory; finite fields.

Accommodations: Any student with a disability is encouraged to meet with me privately during the first week of class to discuss accommodations. Each student must bring a current Memorandum of Accomodations from the Office of Student Disability Services which is prerequisite for receiving accommodations. Accommodated examinations through the Office of Student Disability Services require two weeks notice. All course documents are available in alternate format if requested in the students Memorandum of Accommodations.

FERPA: The Family Education Rights and Privacy act ("FERPA" or "The Buckley Amendment") prohibits USF's release of student information, including grades except under circumstances designed to insure student privacy.

I will not be posting grades, although there are means to make it acceptable within FERPA. Instead, for those too impatient to wait for their final grade to appear, I will provide grade information in response to an e-mail containing the course name/number, your name and student id, along with a request for grade information.

USF policy: Students are referred to the graduate catalog for university policy on academic dishonesty.
Cell phones: There are legitimate reasons to keep a cell phone on during class, such as an on-call job or a sick child. If you do not have such a reason, turn off your cell phone. If you must have a cell phone on during class, give me advanced notice (just before class, or early during the semester if this will be on-going). You may step out into the hall to take your call, and then return to class. If you have not given me notice, you are not welcome to create any further distraction by returning to the class room after your call--you can collect your things after class.

Some Advice

Proofs:
The prerequisites of Algebra I include several courses which have taught mathematical proofs. Nonetheless, writing a mathematical proof may remain difficult for students. There are two aspects to writing a proof at the level of this course which may cause difficulty.
The first part of writing a proof is having an idea of how to proceed. This is the aspect which is less practiced in earlier courses. There is no one way to ensure sucess here, but practice and persistence help. Here are some things to think about in your efforts.
  • What are the definitions of the hypotheses? Of the desired conclusions? You are unlikely to get anywhere unless you know where you are starting and where you are going, so learn the definitions of the concepts involved.
  • Is this similar to a result you already know? Many of the same ideas get used over and over under slightly different circumstances. Review the proofs given in the text and in class.
  • What can we say about an object satisfying the hypotheses? Know the tools/facts which have already been developed.
  • Can you verify the fact for a small, specific example? Can you then extend techniques to the general case?
Sometimes you may find yourself stuck. This is part of the learning process and there is no shortcut. After you have thought about a problem for awhile it is fine to talk to other students or to me. (You are always welcome to come to my office hours). However, you are cheating yourself if you seek out assistance before you have really thought about a problem, and you will find yourself having great difficulty on the exams.
The second part of writing a proof is turning an idea into a rigorous proof. It is often the case in mathematics that we think about problems in one way, but then must write about them in a slightly different way. The work you did to produce an idea must now be cleaned up and turned into a coherent text. I have found that students who really understand their arguments are able write them down much more clearly than those who do not.
In writing proofs, I would recommend the following approach to homework. write the proof and set it aside for a day or two. If, when you return to it, you do not understand what you wrote, then the chances are that it is either incorrect or poorly written (or both). In this case, try again. I know that time may not always permit this, but you might want to try this with one or two problems from homework each week.
Getting stuck, getting help:
There is no shortcut to learning math--you must work out problems to develop and reinforce your understanding of concepts and computations. It is only natural that some of the homework problems resist initial attempts at solution. In fact, getting stuck is an important part of the learning process because it helps isolate deficits in our understanding and forces us to master the material. Thus, it is important that we first seriously attempt to solve a problem ourselves before seeking outside assistance. Outside assistance is not bad, but to seek it out too soon or too often is to cheat ourselves of an opportunity to learn. Indeed hard earned knowledge will stick the longest and the best.

Around the Web

The following websites treat topics relevant to graduate algebra, and may be useful as supplemental sources of information. I can't take any credit or blame for anything on these sites--I did a search and then took a quick look to see that they seemed appropriate. For your consideration are the following:

Online textbook "ABSTRACT ALGEBRA, Second Edition" by John A. Beachy and William D. Blair
Some notes by Bruce Ikenaga
Some notes by J. Brudan
Some problems and notes by Robin Chapman
Online textbook "Elements of Abstract and Linear Algebra" by Edwin H. Connell
Some Materials for the Graduate Algebra Course by E. L. Lady
Some course notes by J. Milne
Online textbook "Abstract Algebra:The Basic Graduate Year" by Robert Ash
Some lecture notes in abstract algebra by D. Wilkins
Course notes by F. Anderson
Course notes by F. Anderson

Here are some other sites that the curious may find of interest. A search will turn of many other sites on the general topics. I've only included those which I have found to have material relevant to the course and which are fairly comprehenseive (I may have missed some, but you can do a search as well as I).
