Text :  Abstract Algebra, 3rd Edition, by David Dummit and Richard Foote. 

Course Meetings:  The course lectures will be held in Humanities 424 on Mondays, Wednesdays and Fridays at 10-10:50 am. 

Topics: Theory of groups, permutation groups, Sylow theorems, introduction to ring theory, polynomial rings, principal ideal domains.

Homework (200 points):  Homework will be assigned weekly on Wednesdays and will be collected the following Wednesday.  Late homework will be penalized 20% off per each day that it is late.  Homework will not be graded unless it is written in order and labeled appropriately.   The definitions and theorems in the text and given in class are your tools for the homework proofs.  If the theorem has a name, use it.  Otherwise, I would prefer that you fully describe the theorem in words that you plan to use, than state “by Theorem 3”.  Each week I will select about 4 or 5 of the assigned problems to grade. The weekly assignments will each be worth 20 points.  I will drop your lowest two homework scores and the remaining homework will be averaged to get a score out of 200. 

Exams (500 points):  I will give two midterms (100 points) and a final (300 points). There are no make up exams. If a test is missed, notify me as soon as possible on the day of the exam. For the midterms only, if you have a legitimate and documented excuse, your grade will be recalculated without that test.  The Midterms are tentatively scheduled for Monday, September 29 and Wednesday, November 5.  The Final is on Friday, December 19, from 7:30-9:30 am. 

Grades:  General guidelines for letter grades (subject to change; but they won't get any more strict): 90-100% - A; 80-89% - B; 70-79% - C; 60-69% - D; below 60% - F.  In assigning Final Grades for the course, I will compare your grade on all course work (including the Final)  and your grade on the Final Exam.  You will receive the better of the two grades.
