This exercise is optional!

Some information on this course:

1. BOOK: Michael Artin, Algebra, Prentice-Hall, Inc.

The edition I'm using is May 1991, which is the only one available
as far as I know.

2. Notation used in listing the exercises: The expression a.b.c
signifies:

Chapter a, Section b, Exercise c.

It can happen that b=M; this refers to the miscellaneous problems
section.

3. Lectures are on MWF, 10-11 in 4-105.

Attendance is strongly encouraged. In particular,
you won't know the material covered if you don't show up!

4. Homeworks assigned: Usually in the Wednesday lecture.

5. Homeworks due: STRICT DEADLINE: Give
your work to me in class on wednesday.

Any late homework that makes its way to the grader
Miki (see below) on Wednesday will

be graded and 50% of the grade will count.

6. Names of grader(s):

Miki Havlickova. E-mail: mikihavl@mit.edu

Office: 2-229. Office hours: Monday 4:30-5:30,
4th floor, building 2, stairwell accross from 2-290.
