MATH 521 - Abstract Algebra

Spring 2015

 

 

Professor: Dr. Janet Vassilev
Office: SMLC 324

Office Hours:  MF 1-1:50, W 10 - 10:50 am and by appointment.

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

Course Meetings:  The course lectures will be held in Mitchell Hall 221 on Mondays, Wednesdays and Fridays at 9:00-9:50 am. 

Topics:  Module Theory, field theory, Galois theory.

Homework (200 points): Homework will be assigned on Wednesdays and collected the following Wednesday at the beginning of class.  Homework will not be graded unless it is written in order and labeled appropriately.  The definitions and theorems given in class and in the text will be your tools for the homework proofs.  If the theorem has a name, use it.  Otherwise, I would prefer you to fully describe the theorem with words, than state by Theorem 3.  Each week 4 or 5 of the problems will be graded.  The weekly assignments will be given a score out of 20 points.  I will drop the lowest two homework assignments and average the remaining to get a score out of 200.

Exams (400 points):  I will give two midterms (100 points) and a final (200 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, February 23 and Monday, April 6.  The Final is on Wednesday, May 6, 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.
