SYLLABUS:
Chapter Three, Groups;
Chapter Four, Polynomials;
Chapter Five, Commutative Rings;
Chapter Six, Fields (6.1-6.2)

COURSE OBJECTIVES: The student is expected to continue learning the basic results on groups, rings, and fields. The concepts of homomorphism and quotient structure (using an appropriate equivalence relation) are of particular importance. The course will end with a proof of the impossibility of certain geometric constructions.
COURSE PREREQUISITE: MATH 420 (you should have a solid C)
GRADING:
Grades will be assigned on the basis of 600 points,
with 2 hour exams worth 100 points each,
homework and quizzes worth a total of 200 points,
and the final exam worth 200 points.
The homework problems are extremely important.
In many ways the course is like an English composition
course, since it requires you to write out very carefully
the reasons for each step in your solutions of problems.
Please note that the last day for undergraduates to withdraw is
Friday, March 5.
FINAL: The final exam is scheduled for Wednesday, May 5, 8:00-9:50 a.m.
