  • Literature:
  • We are going to use: Dummit and Foote, Abstract Algebra (3rd ed.), Wiley 2003; and Prof. R. Elman's Lectures in Abstract Agebra available for download here. And here are the very incomplete notes of mine that I am following.

  • Grading Policy:
    There will be 8 homework assignments, to be handed in in class on Fridays. Late homework will not be accepted. There will also be one midterm exam, and a final exam. The total score for the course will be based on the following: homework will account for 30%, the midterm for 30% and the final will contribute the remaining 40%. This class will use the myUCLA gradebook facility.

    Requests for a regrading will only be considered within 14 calendar days of the due date of the original assignment, and no later than the day before the final. All such requests must be directed to the instructor; the TA is not allowed to make changes to grades.
