Lectures:  Mondays, Wednesdays, and Fridays, 1:30 pm - 2:18 pm (room CL 109).

Prerequisites:  Math 568 (may be taken concurrently) and Math 345.  Not open to students with credit for Math H590.

Course description: The algebra sequence 580-581-582 includes elementary number theory, group theory, vector spaces, linear transformations, and field theory.  It gives a historical introduction to many of the major ideas in modern algebra.  This quarter, we will cover Chapters 0--7 of the text.  We will start with a study of congruence and symmetry that will introduce the concept of a group.  Then, we will move on to solving polynomial equations, a topic that will lead us to rings and fields.


Text:   Abstract Algebra by Ronald Solomon, Brooks/Cole, 2003, ISBN 0-534-39996-7. 

Homework: Weekly homework assignments will generally be due at the beginning of class on Wednesdays.  (All problems will be collected although not all will necessarily be graded.)  The first homework is due on Wednesday, September 28.  Late homework will not be accepted.

Exams: There will be two midterms and a cumulative final.

There will be no make-up exams. Examinations will not be rescheduled because of travel arrangements -- it is your responsibility to schedule travel appropriately.

Grading:

Homework: 100 points
First and second exams: 200 points (100 points each)
Final exam: 200 points
Total Possible:  500 points

Remarks on written work: You are encouraged to discuss the course material with other students.  However, anything that you turn in must be your own work.  Work must be neat and legible in order to be graded. Also, remember that when you are writing up your solutions, your goal is not only to convey that you know how to solve a problem but also to communicate your solution effectively.  Could your solution be understood by a mathematician who has never before solved the problem?  If not, then it is not a complete solution.  Keep this in mind!
