Welcome to Tom Roby's Math 4901 homepage! (Spring 2000)

Math 4901 (Senior Seminar) is designed to be a capstone experience
for students who are about to graduate. It carries two units of
credit, and therefore meets only once a week. This quarter we will
organize it around student presentations. Each student will give 3--4
presentations in class. The other assigned work will be to read a book
or article (that you haven't read before), and write a short report on
it, and to do a few problems based on other lectures.
COORDINATES: Lectures meet Tuesdays 6:00--7:50p.m. (#12052 01) in
Sci Science 247.
TEXT: Fomin, Genkin, & Itenberg
Mathematical Circles (Russian Experience) American Mathematical
Society, Mathematical World, Vol. 7. This has some great problems.
WEB RESOURCE: http://seki.csuhayward.edu/4901.html
will be my Math 4901 homepage. It will include a copy of the syllabus
and list of homework assignments. I will keep this updated throughout
GRADING: Your grade will be based on 3--4 oral presentations
(in class), a report on a mathematics book or article you read, and
homework assigned and graded by your peers.
The breakdown of points is:
| Presentations || Report || HW |
|60% ||20% ||20% |
HOMEWORK: Each presenter will handout a set of five exercises,
which are doable after the lecture. These should be simple enough that
they don't take a lot of time, but not so simple that they can be
answered without any thought. These will be handed in the next
week to the presenter, who will grade them.
REPORTS: Choose an article from the American
Mathematical Monthly or a book to read and write a short 5 page
report on it. If time permits, there may be presentations on these
at the end of the quarter.
Your report should be interesting to read in its own right.

PRESENTATIONS: Each presentation should last 10 minutes
(strictly enforced with a timer!). There will be a couple of minutes for
questions at the end of each presentation. Please handin a typed
summary of your presentation to me, and handout a homework assignment
as described above (make enough copies) to the class. You may choose your
topic from among those given below, or get approval from me for a
